d2af5339af fix offsite sync: use --chmod for Synology permission compatibility 
Synology Administrator user can't create dirs with root-owned permissions
from PVC snapshots. Switch from -az to -rltz --chmod to set writable
permissions on destination. Also updated Cloud Sync Task 1 excludes
to prevent duplication of backup dirs on Synology.

d009f9a0f2 add 3-2-1 backup pipeline: weekly PVC file copy, NFS mirror, pfsense, offsite sync 
- weekly-backup.sh: mounts LVM thin snapshots ro, rsyncs files to /mnt/backup/pvc-data
  with --link-dest versioning (4 weeks). Also mirrors NFS backup dirs from TrueNAS,
  backs up pfsense (config.xml + full tar), PVE host config, and prunes >7d snapshots.
- offsite-sync-backup.sh: rsync --files-from manifest to Synology (no full dir walk).
  Monthly full --delete sync on 1st Sunday. After=weekly-backup.service dependency.
- lvm-pvc-snapshot.timer: changed to daily 03:00 (was 2x daily)
- Prometheus alerts: WeeklyBackupStale, WeeklyBackupFailing, PfsenseBackupStale,
  OffsiteBackupSyncStale, BackupDiskFull. LVMSnapshotStale threshold 24h→48h.
