Make every cancel/back button an outline button

The filled base button reads as heavy as the primary next to it, so cancel is now
btn-outline everywhere it appears: sign out, the 2FA challenge, and the four
control-panel forms (which also gain the back-arrow icon the auth pages already
had).

For the record, the buttons were never different heights -- measured in a real
browser, every .btn on every page is 40px, anchor and button alike. It was the
fill, not the box.
