Adds the portal pair (shadowverse-portal.com deck-builder endpoints) as anonymous routes on the app server. The translation middleware learns a new [NoWireEncryption] attribute that skips both AES calls but keeps the rest of the msgpack + base64 + envelope pipeline intact, matching prod's portal wire profile observed in data_dumps/traffic_prod_deckcode.ndjson. Storage is a 3-minute IMemoryCache — codes are anonymous-global, 4-char lowercase alphanumeric (matches the shortest prod sample). Foil bit is stripped on mint to match prod's normalize-on-encode behaviour. Co-Authored-By: Claude Opus 4.7 <noreply@anthropic.com>
