fix(mobile): fix iOS TurboModule crash and npm install peer dep conflict

- UploadScreen.tsx: replace deprecated ImagePicker.MediaTypeOptions.Images
  with new array syntax ['images'] — the old enum is not accepted by the
  expo-image-picker v17 TurboModule on iOS, causing SIGABRT on Thread 2
- package.json: bump react 19.1.0 → 19.2.4 so react-dom@19.2.4 (peerOptional
  of @expo/metro-runtime) no longer conflicts; update @types/react to ~19.2.0
- package-lock.json: update react entry to 19.2.4 (integrity removed, will be
  regenerated by npm install on the next EAS build)
