Subject: [PATCH] fix: add /healthz endpoint to prevent K8s crash loop

- Added dedicated /healthz route returning 200 OK
- Skip API health check in hooks.server.ts for /healthz path
- Updated K8s liveness/readiness probes to use /healthz instead of /login
- The /login probe was returning 503 when the API was unreachable, causing
  Kubernetes to kill and restart the pod in a loop
