Fix React error #130 - Resolve component import issues

- Fixed wildcard exports in common/index.ts with explicit named exports
- Fixed GalleryView import path in GalleryPage.tsx
- Fixed ToastContainer props formatting in App.tsx
- Ensured all components are properly exported and imported

This should finally resolve the invalid element type error.
