fix: detect ORIENTATION_ROTATE_270 in EXIF rotation check

shouldRotateByExif previously only returned true for ORIENTATION_ROTATE_90.
Some Camera1 devices report ORIENTATION_ROTATE_270 for the same physical
orientation; the function now returns true in both cases so the bitmap
transform is applied correctly on such devices.

Also add markdown language identifier to the summary table code block in
the pr-review skill (MD040 lint fix).
