fix(style): migrate from deprecated github.com/pkg/errors package (#1071)

* refactor: migrate error packages from pkg/errors to stdlib

Replace github.com/pkg/errors with Go standard library error handling
in foundation error packages:

- internal/datastore/errors: errors.Wrap -> fmt.Errorf with %w
- internal/errors: errors.As -> stdlib errors.As
- controllers/soot/controllers/errors: errors.New -> stdlib errors.New

Part 1 of 4 in the pkg/errors migration.

* refactor: migrate datastore package from pkg/errors to stdlib

Replace github.com/pkg/errors with Go standard library error handling
in the datastore layer:

- connection.go: errors.Wrap -> fmt.Errorf with %w
- datastore.go: errors.Wrap -> fmt.Errorf with %w
- etcd.go: goerrors alias removed, use stdlib errors.As
- nats.go: errors.Wrap/Is/New -> stdlib equivalents
- postgresql.go: goerrors.Wrap -> fmt.Errorf with %w

Part 2 of 4 in the pkg/errors migration.

* refactor: migrate internal packages from pkg/errors to stdlib (partial)

Replace github.com/pkg/errors with Go standard library error handling
in internal packages:

- internal/builders/controlplane: errors.Wrap -> fmt.Errorf
- internal/crypto: errors.Wrap -> fmt.Errorf
- internal/kubeadm: errors.Wrap/Wrapf -> fmt.Errorf
- internal/upgrade: errors.Wrap -> fmt.Errorf
- internal/webhook: errors.Wrap -> fmt.Errorf

Part 3 of 4 in the pkg/errors migration.

Remaining files: internal/resources/*.go (8 files, 42 occurrences)

* chore: run go mod tidy after pkg/errors migration

The github.com/pkg/errors package moved from direct to indirect
dependency. It remains as an indirect dependency because other
packages in the dependency tree still use it.

* fix(datastore): use errors.Is for sentinel error comparison

The stdlib errors.As expects a pointer to a concrete error type, not
a pointer to an error value. For comparing against sentinel errors
like rpctypes.ErrGRPCUserNotFound, errors.Is should be used instead.

Co-Authored-By: Claude Opus 4.5 <noreply@anthropic.com>

* fix: resolve golangci-lint errors

- Fix GCI import formatting (remove extra blank lines between groups)
- Use errors.Is instead of errors.As for mutex sentinel errors

Co-Authored-By: Claude Opus 4.5 <noreply@anthropic.com>

* fix(errors): use proper variable declarations for errors.As

The errors.As function requires a pointer to an assignable variable,
not a pointer to a composite literal. The previous pattern
`errors.As(err, &SomeError{})` creates a pointer to a temporary value
which errors.As cannot reliably use for assignment.

This fix declares proper variables for each error type and passes
their addresses to errors.As, ensuring correct error chain matching.

Co-Authored-By: Claude Opus 4.5 <noreply@anthropic.com>

* fix(datastore/etcd): use rpctypes.Error() for gRPC error comparison

The etcd gRPC status errors (ErrGRPCUserNotFound, ErrGRPCRoleNotFound)
cannot be compared directly using errors.Is() because they are wrapped
in gRPC status errors during transmission.

The etcd rpctypes package provides:
- ErrGRPC* constants: server-side gRPC status errors
- Err* constants (without GRPC prefix): client-side comparable errors
- Error() function: converts gRPC errors to comparable EtcdError values

The correct pattern is to use rpctypes.Error(err) to normalize the
received error, then compare against client-side error constants
like rpctypes.ErrUserNotFound.

+                              Notes for implementors:
+
+                              While parents is not a listType `map`, this is due to the fact that the
+                              list key is not scalar, and Kubernetes is unable to represent this.
+
+                              Parent status MUST be considered to be namespaced by the combination of
+                              the parentRef and controllerName fields, and implementations should keep
+                              the following rules in mind when updating this status:
+
+                              * Implementations MUST update only entries that have a matching value of
+                                `controllerName` for that implementation.
+                              * Implementations MUST NOT update entries with non-matching `controllerName`
+                                fields.
+                              * Implementations MUST treat each `parentRef`` in the Route separately and
+                                update its status based on the relationship with that parent.
+                              * Implementations MUST perform a read-modify-write cycle on this field
+                                before modifying it. That is, when modifying this field, implementations
+                                must be confident they have fetched the most recent version of this field,
+                                and ensure that changes they make are on that recent version.

+                                    then that Gateway's controller MUST set the "Accepted" condition on the

+
+                                    A Route MUST be considered "Accepted" if at least one of the Route's

+
+                                    There are a number of cases where the "Accepted" condition may not be set

+                                    map with a key of the `type` field _in the k8s apiserver_.
+
+                                    This means that implementations must obey some rules when updating this
+                                    section.
+
+                                    * Implementations MUST perform a read-modify-write cycle on this field

+                                    * Implementations MUST NOT remove or reorder Conditions that they are not
+                                      directly responsible for. For example, if an implementation sees a Condition
+                                      with type `special.io/SomeField`, it MUST NOT remove, change or update that
+                                      Condition.
+                                    * Implementations MUST always _merge_ changes into Conditions of the same Type,
+                                      rather than creating more than one Condition of the same Type.
+                                    * Implementations MUST always update the `observedGeneration` field of the
+                                      Condition to the `metadata.generation` of the Gateway at the time of update creation.
+                                    * If the `observedGeneration` of a Condition is _greater than_ the value the
+                                      implementation knows about, then it MUST NOT perform the update on that Condition,
+                                      but must wait for a future reconciliation and status update. (The assumption is that
+                                      the implementation's copy of the object is stale and an update will be re-triggered
+                                      if relevant.)

+                                each parent. When this route attaches to a parent, the controller that

+                                first sees the route and should update the entry as appropriate when the

+
+                                While parents is not a listType `map`, this is due to the fact that the
+                                list key is not scalar, and Kubernetes is unable to represent this.
+
+                                Parent status MUST be considered to be namespaced by the combination of
+                                the parentRef and controllerName fields, and implementations should keep
+                                the following rules in mind when updating this status:
+
+                                * Implementations MUST update only entries that have a matching value of
+                                  `controllerName` for that implementation.
+                                * Implementations MUST NOT update entries with non-matching `controllerName`
+                                  fields.
+                                * Implementations MUST treat each `parentRef`` in the Route separately and
+                                  update its status based on the relationship with that parent.

+                                      then that Gateway's controller MUST set the "Accepted" condition on the

+                                      Gateway, and why.
+
+                                      A Route MUST be considered "Accepted" if at least one of the Route's

+                                      due to lack of controller visibility, that includes when:

+                                      * The Route is of a type that the controller does not support.

+                                      Notes for implementors:
+
+                                      Conditions are a listType `map`, which means that they function like a
+                                      map with a key of the `type` field _in the k8s apiserver_.
+
+                                      This means that implementations must obey some rules when updating this
+                                      section.
+
+                                      * Implementations MUST perform a read-modify-write cycle on this field
+                                        before modifying it. That is, when modifying this field, implementations
+                                        must be confident they have fetched the most recent version of this field,
+                                        and ensure that changes they make are on that recent version.
+                                      * Implementations MUST NOT remove or reorder Conditions that they are not
+                                        directly responsible for. For example, if an implementation sees a Condition
+                                        with type `special.io/SomeField`, it MUST NOT remove, change or update that
+                                        Condition.
+                                      * Implementations MUST always _merge_ changes into Conditions of the same Type,
+                                        rather than creating more than one Condition of the same Type.
+                                      * Implementations MUST always update the `observedGeneration` field of the
+                                        Condition to the `metadata.generation` of the Gateway at the time of update creation.
+                                      * If the `observedGeneration` of a Condition is _greater than_ the value the
+                                        implementation knows about, then it MUST NOT perform the update on that Condition,
+                                        but must wait for a future reconciliation and status update. (The assumption is that
+                                        the implementation's copy of the object is stale and an update will be re-triggered
+                                        if relevant.)

+# Gateway API Support
+
+Kamaji provides built-in support for the [Gateway API](https://gateway-api.sigs.k8s.io/), allowing you to expose Tenant Control Planes using TLSRoute resources with SNI-based routing. This enables hostname-based routing to multiple Tenant Control Planes through a single Gateway resource, reducing the need for dedicated LoadBalancer services.
+
+## Overview
+
+Gateway API support in Kamaji automatically creates and manages TLSRoute resources for your Tenant Control Planes. When you configure a Gateway for a Tenant Control Plane, Kamaji automatically creates TLSRoutes for the Control Plane API Server. If konnectivity is enabled, a separate TLSRoute is created for it. Both TLSRoutes use the same hostname and Gateway resource, but route to different ports(listeners) using port-based routing and semantic `sectionName` values.
+
+Therefore, the target `Gateway` resource must have right listener configurations (see the Gateway [example section](#gateway-resource-setup) below).
+
+
+## How It Works
+
+When you configure `spec.controlPlane.gateway` in a TenantControlPlane resource, Kamaji automatically:
+
+1. **Creates a TLSRoute for the control plane** that routes for port 6443 (or `spec.networkProfile.port`) with sectionName `"kube-apiserver"`
+2. **Creates a TLSRoute for Konnectivity** (if konnectivity addon is enabled) that routes for port 8132 (or `spec.addons.konnectivity.server.port`) with sectionName `"konnectivity-server"`
+
+Both TLSRoutes:
+
+- Use the same hostname from `spec.controlPlane.gateway.hostname`
+- Reference the same parent Gateway resource via `parentRefs`
+- The `port` and `sectionName` fields are set automatically by Kamaji
+- Route to the appropriate Tenant Control Plane service
+
+The Gateway resource must have listeners configured for both ports (6443 and 8132) to support both routes.
+
+## Prerequisites
+
+Before using Gateway API support, ensure:
+
+1. **Gateway API CRDs are installed** in your cluster (Required CRDs: `GatewayClass`, `Gateway`, `TLSRoute`)
+
+2. **A Gateway resource exists** with appropriate listeners configured:
+    - At minimum, listeners for ports 6443 (control plane) and 8132 (Konnectivity)
+    - TLS protocol with Passthrough mode
+    - Hostname pattern matching your Tenant Control Plane hostnames
+
+3. **DNS is configured** to resolve your hostnames to the Gateway's external address
+
+4. **Gateway controller is running** (e.g., Envoy Gateway, Istio Gateway, etc.)
+
+## Configuration
+
+### TenantControlPlane Gateway Configuration
+
+Enable Gateway API mode by setting the `spec.controlPlane.gateway` field in your TenantControlPlane resource:
+
+```yaml
+apiVersion: kamaji.clastix.io/v1alpha1
+kind: TenantControlPlane
+metadata:
+  name: tcp-1
+spec:
+  controlPlane:
+  # ... gateway configuration:
+    gateway:
+      hostname: "tcp1.cluster.dev"
+      parentRefs:
+      - name: gateway
+        namespace: default
+      additionalMetadata:
+        labels:
+          environment: production
+        annotations:
+          example.com/custom: "value"
+  # ... rest of the spec
+    deployment:
+      replicas: 1
+    service:
+      serviceType: ClusterIP
+  dataStore: default
+  kubernetes:
+    version: v1.29.0
+    kubelet:
+      cgroupfs: systemd
+  networkProfile:
+    port: 6443
+    certSANs:
+    - "c11.cluster.dev"  # make sure to set this.
+  addons:
+    coreDNS: {}
+    kubeProxy: {}
+    konnectivity: {}
+
+```
+
+**Required fields:**
+
+- `hostname`: The hostname that will be used for routing (must match Gateway listener hostname pattern)
+- `parentRefs`: Array of Gateway references (name and namespace)
+
+**Optional fields:**
+
+- `additionalMetadata.labels`: Custom labels to add to TLSRoute resources
+- `additionalMetadata.annotations`: Custom annotations to add to TLSRoute resources
+
+!!! warning "Port and sectionName are set automatically"
+    Do not specify `port` or `sectionName` in `parentRefs`. Kamaji automatically sets these fields in TLSRoutes.
+
+### Gateway Resource Setup
+
+Your Gateway resource must have listeners configured for both the control plane and Konnectivity ports. Here's an example Gateway configuration:
+
+```yaml
+apiVersion: gateway.networking.k8s.io/v1
+kind: GatewayClass
+metadata:
+  name: envoy-gw-class
+spec:
+  controllerName: gateway.envoyproxy.io/gatewayclass-controller
+---
+apiVersion: gateway.networking.k8s.io/v1
+kind: Gateway
+metadata:
+  name: gateway
+  namespace: default
+spec:
+  gatewayClassName: envoy-gw-class
+  listeners:
+  - name: kube-apiserver
+    port: 6443
+    protocol: TLS
+    hostname: 'tcp1.cluster.dev'
+    tls:
+      mode: Passthrough
+    allowedRoutes:
+      kinds:
+      - group: gateway.networking.k8s.io
+        kind: TLSRoute
+      namespaces:
+        from: All
+
+    # if konnectivity addon is enabled:
+  - name: konnectivity-server
+    port: 8132
+    protocol: TLS
+    hostname: 'tcp1.cluster.dev'
+    tls:
+      mode: Passthrough
+    allowedRoutes:
+      kinds:
+      - group: gateway.networking.k8s.io
+        kind: TLSRoute
+      namespaces:
+        from: All
+    
+```
+
+
+## Multiple Tenant Control Planes
+
+You can use the same Gateway resource for multiple Tenant Control Planes by using different hostnames:
+
+```yaml
+# Gateway with wildcard hostname
+apiVersion: gateway.networking.k8s.io/v1
+kind: Gateway
+metadata:
+  name: gateway
+spec:
+  listeners:
+  - hostname: '*.cluster.dev'
+    name: kube-apiserver
+    port: 6443
+    # ...
+---
+# Tenant Control Plane 1
+apiVersion: kamaji.clastix.io/v1alpha1
+kind: TenantControlPlane
+metadata:
+  name: tcp-1
+spec:
+  controlPlane:
+    gateway:
+      hostname: "tcp1.cluster.dev"
+      parentRefs:
+      - name: gateway
+        namespace: default
+  # ...
+---
+# Tenant Control Plane 2
+apiVersion: kamaji.clastix.io/v1alpha1
+kind: TenantControlPlane
+metadata:
+  name: tcp-2
+spec:
+  controlPlane:
+    gateway:
+      hostname: "tcp2.cluster.dev"
+      parentRefs:
+      - name: gateway
+        namespace: default
+  # ...
+```
+
+Each Tenant Control Plane will get its own TLSRoutes with the respective hostnames, all routing through the same Gateway resource.
+
+You can check the Gateway status in the TenantControlPlane:
+
+```bash
+kubectl get tenantcontrolplane tcp-1 -o yaml
+```
+
+Look for the `status.kubernetesResources.gateway` and `status.addons.konnectivity.gateway` fields.

+When the parent resource is a Gateway, this targets all listeners

+select this Route). It's not recommended to set `Port` unless the
+networking behaviors specified in a Route must apply to a specific port
