fix(03-04): replace CameraCapture with file input capture="environment"

- Remove CameraCapture modal which required getUserMedia (HTTPS only)
- Use native file input with capture="environment" attribute
- Opens camera directly via OS file picker on mobile
- Works over HTTP during development
- Simpler implementation with better browser compatibility
