web: ask before a saved photo goes

Removing a saved frame is not like removing a note: its history goes with it,
and nothing on screen said so. A shared modal now names the photo, warns how
many looks ride along, offers the stored file as a download first, and only
then deletes — from MY PHOTOS in the studio and from the folder page alike.
