feat(statusbar): Select All/Clear All in filter popup, drop osnap settings row

The selection-filter popup now has the same Select All / Clear All header
as the OSNAP popup: Select All clears every exclusion (all types
selectable), Clear All excludes every present type. Each button disables
when it would be a no-op.

Also remove the "Object Snap Settings…" footer from the OSNAP popup.
