feat(maintainerr): deploy for watched-movie cleanup (Plex -> Radarr)

Rule-based deletion of watched movies from Radarr (with files), driven by
Maintainerr. Raw manifests + directory-type Argo Application (no Helm).
Config on shared plex-data NFS PVC (subPath configs/maintainerr); Recreate
strategy since it uses SQLite on RWX NFS. ClusterIP only, no ingress —
access via kubectl/k9s port-forward.
