web: each PICTURES column is an album shelf, a frame and a strip

Both columns now have the shape the curator asked for: a narrow shelf of
albums down the left — one per account on the uploads side, one per landing
section on the other — the frame that is up in the middle, and the open
album's thumbnails as a strip across the bottom.

The frame keeps its labels, the four section boxes, the look's QR code and
the delete button under the picture, where before they sat beside it. Each
column previews its own frame; both obey the same name, sort and rating
filters.
