WalletActionPill
The wallet home's single action pill, split in two: SCAN (read a QR — credential offer or a verifier's request) and PRESENT (show an in-person engagement QR; the verifier's request picks which card is shared). Presenting isn't tied to a card, so it lives here rather than on each card.
Hosts show it on the plain card list only (not while a card is focused or its details are open).
