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.
