Finish the keyboards, and say a state once

Shift+M and Shift+Y reach the month and year dropdowns, which is M3's
date picker keyboard table; Home and End go to the ends of an open
combobox list, and stay the field's own caret keys when it is closed. The
password reveal drops aria-pressed and keeps only its flipping label, so
a screen reader hears the state once rather than twice and inverted. The
radio's `inline` now says that M3 cautions against a row and wants an
option chosen on load.

Plan step 20, findings IN-22, IN-23, IN-28 and IN-29.
