Worker Cards

Worker cards for the @handles an agent mentioned in the thread.

The agent writes "@saratoga_amy"; the console asks for that worker's card so the customer sees who it means rather than a username. The fields are the ones search_workers already hands the customer's agent, minus anything about location, and only for workers search could have returned -- verified and active. An unknown handle is simply absent, so this cannot be used to learn more than search already says.
