portrait-only: drop landscape rotate prompt + lock to portrait

- Remove RotatePrompt (the "rotate to landscape" overlay) — the app is portrait
  now, so it only blocked the UI.
- page.tsx: best-effort orientation lock switched landscape → portrait.
- Add Playwright-based store-screenshot + icon scripts (scripts/shots.js,
  game.js, icon.js); generated images are gitignored.
