Adds the ScheduledBackup CR to source control. Fixes schedule from
5-field to 6-field format (0 0 3 * * *) — CNPG requires seconds as
first field. The broken schedule caused the reconcile loop that
generated 746 stale Backup CRs. Deleted 7 orphaned GitLab Garage
buckets (~8.5 GB) and resumed daily backups.
