Landscape: whole-app landscape-first + Home 2-column landscape layout

- Move orientation lock + RotatePrompt to app root → whole app is landscape-
  first now (UNO-style), not just the game. Generalized rotate copy.
- Home: portrait unchanged; in landscape it becomes a 2-column app layout
  (col A = branding + play actions, col B = tiles + footer) that fits the
  short height with no scroll (landscape: Tailwind variants, overflow-hidden).
