fix: login lag + 📸 overlay visibility + status text

- Login lag: camera/GPS/assets no longer start before login.
  Only initAuth() + initOfflineSupport() run on pageload.
  Camera/GPS/assets start after successful login (or auto-login
  from stored session).
- 📸 capture overlay: was defined in HTML but never shown.
  Now shown when camera starts, hidden when scanning stops.
- Status text: updated from 'Point camera at a barcode' to
  'Point camera at a barcode, or tap 📸 for text stickers'
