iPhone file classification by filename pattern

iOS helper: classify_iphone_file() groups photos by name pattern:
- Camera: IMG_XXXX.{HEIC,JPG} — camera originals
- Edited: IMG_EXXXX.{HEIC,JPG} — Photos.app edits
- Videos: IMG_XXXX.MOV and other video files
- Screenshots: any .PNG (iPhone camera never produces PNG)
- Screen Recordings: RPReplay_Final*.mp4
- Other: everything else (web saves, app exports, etc.)

ExifFilter.isCameraRollFolder: Camera and Edited are camera-roll,
Screenshots/Screen Recordings/Other are not.

sourceFolder now reflects these groups instead of raw DCIM folder names
(145APPLE etc.) so the left panel shows meaningful categories.
