refactor(cleanup): dead code + hygiene batch from games review

- Delete unused ui/theme/Color.kt (zero refs; live palette is Theme.kt).
- Remove orphaned EditProfileScreen wrapper composable (no route references it;
  AccountScreen embeds EditProfileContent, which stays).
- Debug-gate ArtPreviewScreen + PairedHomePreviewScreen out of the release nav
  graph (BuildConfig.DEBUG).
- Collapse duplicate wheel_history route into game_history (same screen; wheel
  surfaces now navigate to Past Games directly).
- CouplePremiumChecker: inject AuthRepository instead of raw
  FirebaseAuth.getInstance() (finishes the in-flight auth-DI refactor for
  non-data-layer call sites).
- Copy/UI polish: 'It's a match!' (matches the push copy), internal 'mc' token
  never renders in the Home daily pill ('Daily Fun Mc' → 'Daily Fun'),
  welcome/splash privacy tagline no longer clips mid-sentence (maxLines 4 +
  ellipsis, AUTH-TRUNC-001).

Unit + functions suites green; assembleDebug clean.
