test(qa): open the phone tab sheets in phone-width harness checks

At 720px and narrower the panels live in the phone shell's tab sheets, so the
camera, scene and map-source tray harnesses open the matching tab (from the
keyboard where they check focus rings) before measuring, wait for the shell to
follow a viewport change, measure the container that actually scrolls, and run
the pin and compact-wing checks at 800px where the narrow desktop dock still
exists.
