* feat(service): add ipFamilyPolicy and ipFamilies to control-plane Service
Expose the native Kubernetes Service IP-family fields on
spec.controlPlane.service so a Tenant Control Plane can be exposed as
dual-stack, IPv4-only, or IPv6-only. Konnectivity shares the same Service
and is covered implicitly. When unset, behaviour is unchanged.
Cross-field CEL enforces SingleStack<=1 family and family uniqueness. No
immutability, preserving the Kubernetes-supported single-stack to
dual-stack upgrade.

* feat(service): pass IP-family config through to the generated Service
Copy spec.controlPlane.service.ipFamilyPolicy and ipFamilies onto the
managed Service only when set, leaving API-server-defaulted values in
place otherwise.

* test(service): cover IP-family CEL and enum validation on TenantControlPlane
Envtest admission specs: IPv6-only and dual-stack accepted; SingleStack
with two families, duplicate families, and an invalid family value are
rejected with their respective CRD validation messages.

* docs(service): clarify dual-stack ipFamilyPolicy expects two ipFamilies
Document that PreferDualStack/RequireDualStack describe a dual-stack
Service and expect two ipFamilies entries, and that an unsatisfiable
RequireDualStack surfaces as a reconcile error, so both over- and
under-specification failure directions are predictable.

* feat(certs): include all control-plane Service IPs in the API server SANs
Derive the API server certificate SANs from every IP the control-plane
Service answers on -- all of its ClusterIPs (both families of a dual-stack
Service) and all LoadBalancer ingress IPs -- so a dual-stack Service is
reachable over both families. The endpoint advertised to clients stays the
primary address; the extra entries only permit TLS over the secondary family.
IPs are deduplicated canonically against the management/advertised address
and existing SANs, so a single-stack Service adds nothing and the certificate
does not churn.

* fix(dns): align IPv6 DNS service IP with kubeadm's 10th-address convention
The DNS service IP defaulting added +16 to the last byte for IPv6 (yielding
fd00::10) while kubeadm and CoreDNS use the 10th address of the service
subnet (fd00::a). The kubelet's cluster DNS then disagreed with the actual
CoreDNS Service ClusterIP, breaking DNS for IPv6-only tenants. Use +10 for
both families, matching the IPv4 path and kubeadm.

* 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.

- Use errors.Is instead of errors.As for mutex sentinel errors

* 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.

* 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.

This also includes converting OnUpdate() to a no-op, as the
existence and immutability of the fields are already checked
by the API server, thanks to kubebuilder markers.
The webhook ensures that fields like dataStore, dataStoreSchema
are defaulted during creation (if unset), and the CEL expressions
prohibit unsetting them during update.
