Subject: [PATCH] feat(cleanup): auto-expire inactive rooms daily

Adds deleteInactiveRooms() function to db.ts that finds and removes
rooms
where the most recent item or vote activity is older than 30 days.

The cleanup runs automatically on server startup and then every 24 hours
via setInterval. Foreign key CASCADE constraints handle automatic
deletion
of associated items and votes.

Implements: b3d438a
Assisted-by: Claude Sonnet 4.5 via Crush
