Used cards: counter quote tag instead of client-temporary feature; item type Material

Client-temporary features are stripped when an item sits on the front
counter, so the scam markup never applied. The quote now lives in a tag and
counts only while the item is not owned. GPU item type ELECTRONIC has no
translation in the game, so cards are typed as Material.
