Proudlock f1ed2b19cd Fix backup system - offline restic package approach ...

PROBLEM: Corporate proxy (Zscaler) blocked ALL package downloads during
Docker build - Oracle Linux yum, Alpine apk, even with SSL certs.

SOLUTION: Offline package approach
- Pre-download restic binary on host (works outside Docker)
- Bake binary into repo at scripts/backup/offline-packages/
- Updated Dockerfile.backup to use offline binary (no downloads)
- Simplified: mysql:8.4 base + offline restic only (no Python/alembic)

RESULT: Backup containers build successfully behind corporate proxy

FILES:
- scripts/backup/offline-packages/restic_0.17.3_linux_amd64.bz2 (8.6MB)
- scripts/backup/Dockerfile.backup: Use offline package, no downloads

VERIFICATION:
- docker compose build backup: SUCCESS
- Backup watcher running: Polling every 30s
- Backup store running: restic REST server on port 8000

WORKING:
- Click 'Back Up Now' in UI
- Watcher detects sentinel file within 30s
- Backup executes automatically

The offline package can be checked into git for easy deployment at
other sites behind similar proxies.
