fix: flip portrait rotation direction so the EPD shows the photo upright

The first rotation pass picked CW server-side / CCW preview-side based on
"ribbon on left" → user rotates frame 90° CCW. On hardware the photo came
out upside down, which means the user's physical rotation is the opposite
of what was assumed: 90° CW from landscape native, putting the ribbon to
the left from the user's POV but to the right from the EPD's reference
frame. The two rotation signs always need to stay opposite — flipping
both keeps the webapp preview upright while fixing the device.

Also drops the temporary upload debug log; the cropOrientation persistence
issue resolved on its own once Doctrine's metadata cache was cleared.
