fix(ui): let ConfirmButton's dialog wear the destructive style

ConfirmButton took a `destructive` prop and dropped it on the way to its
dialog, so every delete, revoke and remove built on it confirmed with a
neutral primary button while ConfirmDialog confirmed the same kind of act
in red. The prop is forwarded now, and the call sites whose act takes
something away pass it. A guard holds every confirmation whose slot names
a destroying act to the destructive style; resets stay neutral.
