69f7289b4a feat(backup): declare server databases + fail safe to stop on dump failure
- Add libreportal.backup.db labels to the MariaDB/Postgres apps (nextcloud,
  owncloud, bookstack, mastodon, invidious) so they back up live + consistent.
- If a declared dump cannot be taken (DB down, wrong path), the backup falls
  back to stop-snapshot-start for that run instead of snapshotting torn data —
  a misconfiguration degrades to 'safe with downtime', never to 'unsafe'.

d9f2feef05 feat(backup): consistent live database backups with auto strategy
Adds a logical-dump path so apps with a database can be backed up with zero
downtime and full consistency, instead of stopping the container.

- backup_db.sh: dump each declared DB live (mysqldump --single-transaction /
  pg_dump / sqlite3 .backup), exclude the raw data dir from the snapshot, and
  replay the dump on restore (pre-start rehydrate for sqlite, post-start load
  for server engines).
- Databases are declared via a 'libreportal.backup.db' compose label so the
  metadata travels with the app in the snapshot.
- New 'auto' strategy (now the default): live where a DB is dumpable or the app
  is marked live-safe, stop-snapshot-start otherwise. Explicit stop/pause/live
  remain as overrides.
- restic/borg/kopia adapters honour an exclude list on the live path.
- Manifest records the resolved per-app strategy and dumped databases.
