fix(room): add cascade deletes and fix QuerySelect trait import

- Import room_message_reaction, room_message_edit_history, room_notifications modules
- Fix room_message_edit_history: no Room column, use subquery via messages
- Change publish_project_room_event from Result to () handling
- Add QuerySelect import for limit() method in workers.rs
