Allow watchdog to clean up timed-out waiting mounts - #296

When a new NFSv4 mount is not progressing and its timeout (180s) has expired, the watchdog should clean up stunnel so that further mounts can succeed. Previously, the NFS server refs guard in /proc/fs/nfsfs/servers blocked cleanup for all entries regardless of status, preventing recovery. Now the guard is only applied to mounted entries where k8s pods may still hold mount namespace refs. 'waiting' entries with expired timeouts bypass the guard so stunnel can be restarted.
