feat: guest reservations and messages with proper table names

- Remove Reserve button from rooms page
- Calendar modal now supports direct reservation for guests
- Message modal works for guests (asks for name, contact method, contact)
- Create room_reservations table (separate from restaurant reservations)
- Create messages table for room inquiries
- LEFT JOIN users in queries to include guest reservations/messages
- Auto-fill form for logged-in users, show input fields for guests
