gsxdsm 4bb3af220e fix(dashboard): mobile keyboard scroll lock, auto-reload hash, ChatView snap
- Add useMobileScrollLock hook using position:fixed body lock (Bootstrap/
  Headless UI/Stripe pattern) to prevent iOS Safari from shifting the
  document and visualViewport when an input inside a fixed-position modal
  is focused. Wire into 15 input-bearing modals plus ChatView, replacing
  ChatView's inline body-overflow effect.
- Widen computeBuildVersion in vite.config.ts to hash the entire app/ tree
  so the version-check poll actually notices rebuilds (FN-3333 follow-up;
  previously only main.tsx and package.json were hashed).
- ChatView: on input blur, suppress keyboard-aware sizing for 450ms while
  reserving mobile-nav-bar space, so the composer snaps to its final
  height in one move instead of crawling down with iOS's keyboard slide
  and then jumping again when the nav bar reappears.
