Back up the database automatically on every compose up

A one-shot backup service runs before the app starts (depends_on
service_completed_successfully; compose re-runs exited one-shots on
every up), so the plain docker compose pull + up -d update flow always
snapshots the database first. Uses SQLite's online-backup API via
better-sqlite3 from the app image itself - safe against the live WAL
database, no downtime, no extra tooling. Backups land in ./backups
(newest 14 kept); a failed backup blocks the app from starting rather
than updating without a safety net.
