fix: support Codex ultra effort

 ### Fixed
 
+- Accept the `ultra` Codex reasoning effort when the selected model advertises support for it.
 - Recheck persisted Codex subscription authentication with a fresh client after a failed completion check; distinguish provider failure from unavailable verification and log only safe outcome categories.
 - Show every reported Codex allowance bucket, with the legacy usage response as a fallback, and accept Windows line endings in the nested security-test fixtures.
 - Run module-mocked security suites in the default test command and reject silently skipped nested test runs.

 OpenAI reports rerouting during a turn, Claudify rejects the result without
 retrying or bypassing the reroute; usage or an action may already have occurred.

 exist elsewhere on the host.
