Revoke API Data

What This Removes

This removes the saved API-key hash and encrypted key material, clears the browser shop session, deletes the short-lived API response cache tied to that key, pauses active public listings, disables public buy prices, and hides the tienda from public browsing.

The player identity record, Cartel Empire player id, last synced non-secret game data, historical market snapshots, and non-secret marketplace activity may remain server-side for integrity, abuse prevention, and aggregate market history.
