Luis Pater dde250f1c3 fix(auth): enable model cooldown and rotation for model not found errors ...

- Map upstream `model_not_found` errors to HTTP 404 before evaluating generic invalid request types in Codex terminal error handling.
- Prevent treating structured model not found responses as client request faults to preserve credential rotation.
- Recognize model access denial errors to apply model-level cooldown and failover.
- Respect `disable_cooling` configuration during model-level cooldown processing.

Closes: #5635
