fix: correct EXIF GPS data extraction using exifr.gps()

The previous implementation was using exifr.parse() with pick option,
which doesn't work for GPS coordinates since latitude/longitude are
computed values, not direct EXIF fields.

Changed to use exifr.gps() method which properly extracts and computes
GPS coordinates from EXIF GPSLatitude/GPSLongitude fields.

This fixes the issue where photos with GPS EXIF data were showing
'No GPS data' in the UI.
