fix: resolve room state synchronization and player display issues

- Fix room.state.players undefined error on component mount
- Wait for initial state sync before accessing room data
- Move message handlers from service to Game component
- Fix player count display in waiting screen (was showing 0/2)
- Prevent lobby component from clearing game room on unmount
- Separate leaveLobby() and leaveGame() methods for proper cleanup
- Ensure player names persist when moving from lobby to game
- Add proper error handling for state initialization
