Fixed QS tiles incorrectly clipping in landscape shade

When shade is in full width mode in landscape (i.e. on phones),
the QS tile clipping was incorrect due to the QS container view
having an inset to avoid the camera cutout. This inset needed to be
accounted for so the clipping would accurately mimic the shape of
the notifications scrim, which does not have an inset.

This only fixes the visible mismatch in QS tile clipping in landscape
mode; it does not fix the very subtle ~1-2 pixels mismatch in
QS tile clipping that is consistently visible in any orientation and
is most likely an anti-aliasing issue(?)

Test: Manually verified QS tile clipping appears correct
