Add game restart and disconnect support

Prevent handling disconnects for games already ended; add a disconnect() method on the SignalR connection and a LocalGame.disconnectAll() helper. Update GameEndedMenu to emit a restart event and adjust displayed messages/labels. Wire a restart() handler in LocalMode that disconnects all players then restarts the game.
