web: re-save over the open frame, keeping its last three looks

Opening one of the folder's own photos and hitting SAVE PHOTO used to
make a second copy of it. Now it replaces that row — same id, same place
— and the look the row carried steps into its history, newest first and
capped at three, because the pixels it described are gone. The frame's
own column in MY PHOTOS lists those looks (click one to put its settings
back on the stage) and carries the landing-page consent as a plain tick,
which answers the click at once. A file from the disk clears the open
id, so a fresh frame still adds one.
