Remove capture=environment from manual photo input — plain file picker preserves EXIF

- manPhotoInput now uses accept=image/* without capture attribute
  -> opens gallery/file picker which gives raw file bytes (EXIF preserved)
- Camera shortcut preserved via openManualCamera() creates a temp
  capture=environment input for quick field capture (no EXIF but available)
- Label updated: 'Tap to take photo' -> 'Tap to choose photo'
- Manual photo capture row references openManualCamera() instead
