Erich Blume c1e7497e12 Add offsite backup for immich photo library to BorgBase 
Adds a second borgmatic config (photos.yaml) that backs up /Volumes/photos
(sifaka SMB mount) to a dedicated BorgBase repo, running daily at 4 AM.
Refactors borgmatic metrics to support multiple repos with a `repo` label,
and updates the Grafana dashboard with a repo selector variable.

Immich Photo Library (Offsite Only)

The immich photo library lives on sifaka at /volume1/photos (SMB-mounted on indri as /Volumes/photos). Since sifaka is already the local backup target, photos are backed up to BorgBase offsite only — not back to sifaka.

Property Value
Config ~/.config/borgmatic/photos.yaml
Schedule Daily at 4:00 AM (offset from main backup)
Source /Volumes/photos (sifaka SMB mount)
Target BorgBase borgbase-immich-photos repo
Size ~128 GB

Uses the same encryption passphrase and SSH key as the main borgmatic config.

Sifaka-Native Data

Other data lives directly on sifaka (music via navidrome, video via jellyfin). See sifaka for data protection details.
