[Server] Shuffle and reorder player seats before a game starts
Auto-shuffles the seats at game start when enabled (now for games with two or more players instead of three or more) and handles the new SET_PLAYER_ORDER command so the game host or a moderator can reorder or randomize the seats before the game starts. Re-seating re-keys the player ids while keeping the per-user game/seat routing and persistent player records in sync, then broadcasts the new order to everyone.
