Subject: [PATCH] Auto-delete ended games after delay

Schedule game removal after a short delay when a game ends. Adds ScheduleGameDeletion which starts a background task, waits (5s), checks the repository for the game and its Ended state, destroys it, and notifies the hub with "GameDestroyed". Calls to ScheduleGameDeletion were added after Win, Draw, and PlayerDisconnected; PlayerDisconnected no longer returns the SendAsync task but returns a completed task after scheduling deletion.
