fix: apply EXIF orientation when loading images from Immich

PIL opens JPEGs without applying EXIF rotation. Immich computes face
bounding boxes on orientation-corrected images, so portrait photos
produced misaligned crops (showing chins/eyes/foreheads instead of
whole faces). ImageOps.exif_transpose() normalizes orientation before
any coordinate math.
