Adds a process-wide toggle that makes podinfo respond with HTTP 500 to all application endpoints while keeping Kubernetes probes, metrics, pprof and the control endpoints functional. This allows a single replica to be made selectively 'sick' to test client-side circuit breakers / outlier detection (Envoy, Istio DestinationRule.outlierDetection, etc.) without Kubernetes evicting the pod.
New endpoints:
POST /fault_injection/enable
POST /fault_injection/disable
GET /fault_injection/status
Includes unit tests for the handlers, the middleware behavior, and the path exclusion list.
Regression test for CVE-2026-43644, mirroring the TestStoreReadHandler_ContentType
test added in #463. Verifies the echoHandler direct-response branch returns
application/octet-stream, X-Content-Type-Options: nosniff, and a restrictive CSP
so an HTML payload cannot be MIME-sniffed and executed.

Validate that the hash URL parameter matches the expected SHA1 hex
format (40 lowercase hex characters) before using it in file path
operations.

Set Content-Type to application/octet-stream in storeReadHandler
to prevent Go's content sniffing from serving HTML payloads as
text/html. Add X-Content-Type-Options: nosniff to prevent browsers
from overriding Content-Type via MIME sniffing, and
Content-Security-Policy: default-src 'none' to block script
execution as defense-in-depth.

Now it is possible to use the swagger webinterface
running on a host other than localhost e.g. in docker
or kubernetes.
Removed the @host line from pkg/api/server.go and
ran make swagger.
Fixes probably #179
