Build 24: equal-size buttons in the release-username confirm gate

"Keep it" used big_action_on_card (56px / 17px) while "Release it" used
big_action_on_card_ink (44px / 15px), so the two confirm buttons were
visibly different sizes. Both now render with big_action_on_card_ink at the
intended 44px (matching the layout's scope), differing only in text color.
