fix(offline): unify NewGame layout to natural-flow + PinPad verdict pause

- NewGame: all three forms (quick / friends / hotseat) now use the
  Profile sub-view's natural-flow .page (no forced height, no pinned-CTA
  .grow/.fg scroll), so the screen's single .content scroll + --vvh handle
  overflow and a focused name input scrolls into view cleanly — fixes the
  keyboard blank-space / deep-scroll regression. One layout rule, one place.
- PinPad: pause 250ms after the 4th digit before the verdict, so the fill
  (and the shake on a wrong PIN) reads as a deliberate response.
- e2e: typePin waits for empty dots before typing (robust to the pause).
