- gitlab: Fix sync-admin-job secretKeyRef schema error, fetch password via kubectl
- nextcloud: Remove duplicate PVC, remove invalid pod-level securityContext
- rook-ceph: Update cephfs-smb-pvc to 50Gi, remove unsupported dashboard.config
- nessus: Add privileged PSS label for NET_ADMIN/NET_RAW capabilities
- scylla-manager: Add privileged PSS label for SYS_NICE capability
