Keep the view on the photographs after some of them are deleted

Deleting made the grid go blank and jump somewhere arbitrary. Two causes, both
of them the viewport being left behind by everything else that moved.

The Flickable is sized to the *whole* library so its scrollbar is a real
address into twenty thousand images. Delete some and that content gets shorter,
which leaves a view near the end scrolled past what now exists — cells sitting
above a viewport looking at empty space. Slint does not pull a Flickable back
on its own. (The clamp for that went in with the previous commit.)

The jump is the other half. Cells are drawn at their absolute place in the
library, `(i + offset) / columns`, and a delete re-clamps `offset` downward so
the loaded window still fills. Nothing touches `viewport-y`, so the same scroll
position now addresses different photographs and the grid appears to leap
somewhere unrelated.

`restore_position` re-anchors on the ordinal the view was showing, clamped into
what is left. Not on the deleted image's own position, which no longer exists,
and not on the top of the library, which would throw the scroll position away
on every delete — after removing one frame from a wall of twenty thousand, the
one you want next is the one that just moved into its place.

Only on a shrink, and the shrink is detected by reading `library-total` before
overwriting it. Re-anchoring on every load would fight a scrub, which sets
exactly this property to go where the user asked.
