0104 was already implemented and already in the action catalogue; nothing
routed to it, so the only way to see the device's list was as a side
effect of writing a card. It has an endpoint now, and the panel a button.
The two lists are compared where they meet: a card the charger holds and
the account has forgotten still opens it, and a card only the account
holds will not, and neither shows anywhere else. The comparison is drawn
only when they disagree, and the device's reading is dropped on a refresh
rather than measured against an account list from a later moment.
The new test asks all four card routes without a token: a capability the
plugin implements and the catalogue advertises is still unusable if
nothing routes to it, and no other test here would notice.
