feat: border move/resize controls work at any zoom

get_border_zone returned None outright in Overview and the motion path
gated hover on mode == Normal, so the resize controls neither revealed
nor worked at any zoom other than 1 — even though the zone math, band
scaling, and the snap/resize pipeline were already zoom-aware. Drop
both gates and split the overview press three ways: a border-band press
falls through to the normal zone handling (resize/move, zoom-aware), a
content press keeps the whole-window overview grab (drag moves, tap
zooms into the window), and only a true background press exits
overview. Verified nested at zoom 0.83: right-edge drag resized
798->936 with the left edge anchored, overview mode retained; content
drag/tap and background exit unchanged.
