Add a standalone Job manifest mirroring the cleanup logic the operator
executes via cleanUpJobTemplateSpec when a CephCluster is deleted with
cleanupPolicy enabled.
Useful when the operator-managed cleanup did not run (e.g. force-deleted
cluster) or a node needs manual cleanup outside normal operator flow.
Secrets (ROOK_MON_SECRET, ROOK_CLUSTER_FSID) are sourced from the
rook-ceph-mon secret via secretKeyRef. Namespace is injected via the
Downward API. Only dataDirHostPath and node hostname need manual input.
