Add health probes to registry deployment to auto-recover from stale NFS mounts
Added startup, liveness, and readiness probes to the docker registry deployment.
The liveness probe will automatically restart the pod when it returns 503 errors
(which happens when NFS storage becomes stale), preventing prolonged ImagePullBackOff
issues for dependent services like radicale and git-server.
