Messaging · GIF picker: a GIF focused past the fold scrolls into view

Each GIF holds its own focus handle, and a canvas around it, ring and
all, sets the results box's offset once per focus from its painted
bounds. layout::bring_into_view now works along either axis; the data
table's header and the video timeline pass their sideways one.
