fix(offline): scope the medal treatment to hotseat only

Per owner: a vs_ai game (one human) keeps its 'you won/lost' status text
AND its lobby medal — the hidden-status + per-seat-medal treatment applies
only to hotseat, where 2-4 local players make a single 'you' meaningless.
isLocalGameId -> game.hotseat at the three call sites (statusBlock, seat
plaque, lobby card).
