test: agent-less CI compat for transport-port tests

The new normalize test now stubs agent.anthropic_adapter in sys.modules
(CI has no agent package — real import raised ModuleNotFoundError), and the
issue-1013 codex fake ports to the v0.21 _get_transport contract instead of
the deleted _normalize_codex_response method.
