feat: add room by name endpoint for non-authenticated access

- Add GET /rooms/name/{room_name} backend endpoint
- Endpoint supports non-authenticated access for public rooms
- Returns RoomDetails with webhook fields hidden for non-owners
- Update useRoomGetByName hook to use new direct endpoint
- Remove authentication requirement from frontend hook
- Regenerate API client types

Fixes: Non-authenticated users can now access room lobbies
