Match intro "players joining" loading screen + i18n fix; checkpoint

- MatchIntroOverlay: UNO-style pre-game reveal — the 4 seats animate into the
  table (with "?" placeholders until each player's data streams in for live
  matches), a 3-2-1-GO countdown, then the table shows. Wired via game-store
  matchIntroPending/consumeIntro, rendered online-only in GameScreen.
- Fix: intro.found / intro.getReady / intro.go existed only in the Persian dict;
  added the English strings (would have shown raw keys to EN users).
- Checkpoint of the in-progress UI/social batch (CoinsPill, shop titles section,
  friend-request rate limit, etc.) — all green.

Verified: tsc + next build + scripts/sim.ts + dotnet build server/Hokm.slnx all pass.
