fix(offline): unlock finished hotseat games + raise entry budget to 120

- source: a finished hotseat game is never locked (its final rack is
  shown for review, not an Unlock button); guard locked on !isOver.
- bundle-size: raise the app-entry budget 115 -> 120 KB for the hotseat
  UI (PIN pad, roster, host menu), which lives in the always-loaded New
  Game / Game / Lobby screens; the offline engine + PIN hashing stay lazy.
