fix(admin): re-request a rotated photo even when the turn failed (#301)

The turn handler only bumped the cache-busting version on the success path, so a failure between the backend's two writes (displayed file rotated, then pristine original rotated) left the admin looking at an error toast next to a photo whose src string had not changed and whose bytes the browser still served from cache — even though the displayed file on disk had already turned. The design's stated mitigation for this failure, that the admin can see the photo moved and press back once, depended on the browser re-requesting the file regardless of outcome. Moving setVersion(Date.now()) into the finally block, alongside setTurning(false), makes that re-request happen on both the success and failure paths, so the failure is now visible and recoverable the way the design intends.
