fix: bot games now create real match record (appear in match history)

Previously bot games used matchId='local' which meant no DB record was
created. Now on bot game start, calls game.php 'start' to insert a real
match row. When game completes, the 'complete' action updates that row
with result/fen/pgn/rating. Matches now appear in مبارياتي.
