List this account’s API keys (never their values)

A key never makes or changes a key into more than it has itself: every group at or under its own level, its scope inside its own (a workspace key makes keys only for that workspace, never one for every workspace), and an expiry no later than its own when it expires. It changes or revokes only keys already within its own access, and only narrows itself; anything past that is 403 key_escalation. A signed in session may do anything to its own keys. A computer’s own key manages no keys (403 computer_key), nor does a key for one computer (403 computer_scope). An expired key answers 401 key_expired. Lists only the keys inside the caller’s own scope (a workspace key sees that workspace’s). Needs API keys read.
