Add bot play, replay creation, and move phrases

Create replay games when a match ends (win or draw) and include ReplayGameCode in the GameEnded payload; adjust deletion timing to keep the replay longer and clean up original games sooner. Update game deletion logic to only destroy non-running games and schedule immediate deletion for quick timeouts. Add optional local bot support (botPlayer2 flag) with automated random-delayed moves and a UI switch in the game creation menu; expose botPlayer2 in GameSettings and LocalMode defaults. Introduce RandomPlaceMessage utility to generate varied turn descriptions and integrate it into LocalGame and OnlineGame. Also include a minor whitespace fix in Game.cs.
