Juhn-Vitus Saß 0068e162f7 feat: Add real-time quiz lobby functionality
- Implement WebSocket-based lobby system for quiz participants
- Add lobby page with real-time participant updates
- Create LobbyConsumer for WebSocket communication
- Add routing configuration for WebSocket connections
- Update requirements with WebSocket dependencies
- Add development and production server documentation

This change enables real-time quiz lobbies where participants can
join and wait for the quiz to start, with instant updates for all
connected users.
