Full-screen camera with photo library option

- Change to fullScreenCover for immersive camera experience
- Add action sheet with 'Take Photo' and 'Choose from Library' options
- Renamed ImagePickerView to support both camera and library sources
- Both options open full-screen for better UX
- Updated accessibility label to 'Add photo' (more accurate)
