Subject: [PATCH] feat: daily volume-snapshot backup for wynnsource-pg

- backup.volumeSnapshot via the longhorn-snapshot VolumeSnapshotClass
  (snapshot-controller now runs in the cluster)
- daily ScheduledBackup at 03:15; retention handled centrally by the
  cnpg-backup-prune CronJob in cnpg-system (keeps newest 14)
- explicit storageClass and resource requests, matching the conventions
  now used by the gitea/zitadel clusters in k3s-gitops
