        Test CRUD operations for Agents.

        This test creates two agents, the first one with two versions, the second one with one version.
        It then gets, lists, and deletes them, validating at each step.
        It uses different ways of creating agents: strongly typed, dictionary, and IO[bytes].

        Routes used in this test:
