gallery: split Take Photo vs Pick from Gallery inputs

- Two dedicated <input> elements: cameraInput (capture=environment) for
  direct camera, galleryInput (no capture) for gallery picker
- Both wired to handlePickedPhoto() via a shared wireInput helper
- refreshGPS() fires on button click (before picker opens) for a fresh
  high-accuracy GPS fix — no maximumAge, so it pulls current location
  instead of relying on cached values from page-load initGPS()
- Workaround for browser EXIF GPS stripping: camera captures may preserve
  EXIF GPS, gallery picks fall through to device geolocation API
