Detect Live Photo companions and show video file size

iOS helper: classify_iphone_file now detects Live Photo MOV companions
by checking if IMG_XXXX.MOV has a matching IMG_XXXX.HEIC/JPG in the
same DCIM folder. Falls back to size heuristic (<5MB = Live Photo).

Live Photo companions appear in 'Live Photo' group (Other section) —
excluded from camera-roll default selection.

DenseThumb: show file size on video badge (e.g. '▶ 2MB' or '▶ 42MB')
so Live Photo clips (small) are visually distinct from real videos (large).
