      Service accounts and their API keys. A human Org Admin manages the service
      accounts of their own organization: create, read, update, and
      enable/disable (there is no delete — an account is disabled instead), and
      issue, rename, re-date, enable/disable, and revoke each account's API
      keys. An API key is an `fks_` secret that inherits the account's grants
      and cannot manage service accounts; an active, unexpired key must be
      disabled before it can be revoked, and it authenticates only while both it
      and its account are active. Scopes here are capability scopes (what the
      account may do), not OAuth scopes.
