Give an unlabelled checkbox, radio or switch a 48px target

A selection control with a label is pressed anywhere along its row, but
one without — a table's "select all", a row's tick — was only its 18, 20
or 32px box, because the 40px state layer is a ::before that catches no
pointer. The box now wears the shared touch-target utility, which M3 asks
for on all three (checkbox, radio and switch specs: target size 48dp).

Plan step 13, finding IN-03.
