feat: orientation toggle and mismatch indicator in crop editor

The crop tool now exposes a landscape/portrait toggle next to the
device-name label, and the canvas crop frame snaps to the chosen
aspect when toggled. Choosing an orientation that does not match
the target frame's current orientation surfaces a yellow informational
chip — purely informational, no action required, clears as soon as
the user toggles back to the matching orientation (or changes the
frame in Settings).

The chosen orientation rides along on the upload/reprocess request
as a new cropOrientation form field and is persisted on the Image
entity, so the library view and rotation logic can later surface
the same mismatch state for already-uploaded photos. Existing photos
without a stored orientation get null and are unaffected.
