Cards: appearance follows wear, hash depends on fan and contacts, seller confrontation

Fan, contact and scratch levels are recomputed from health and a per-card
seed, so a card looks older as it wears. Fan and contacts scale hashrate.
Each inspection-tray detail now maps to exactly one dimension value. Quoting
dealers price the card as if its condition were fine; the player points out
fan, contacts, bracket, print or sticker in the tray to take the matching
discount or expose a fake (a wrong accusation costs reputation like the
vanilla confrontation). Unowned cards show a coarse grade and rated specs.
