* fix: prevent stale chunk errors after deployments

- Set Cache-Control no-cache on index.html in nginx so browsers always
  fetch fresh chunk references after a deploy
- Auto-reload on chunk load failures (stale deploy detection) with
  loop prevention via sessionStorage
- Show friendly "App Updated" message if auto-reload doesn't resolve it
