Tracks outstanding challenges in the configured database across application instances.
The transport retains the challenge and its approved subject and policy. This module stores
only a digest and expiry. Consume the record before verification, outside any transaction
that could roll back after a handler fails. Database errors propagate; they never authorize
verification. Applications may schedule delete_expired/0 to remove abandoned challenges.
