test(integration): happy path end-to-end con escenario MOS sin HITL

Invoca el agente real incident_analyzer (assets del repo, LLM mock) vía
TestClient y comprueba status=completed, final_output y que el decision_path
recorre los seis nodos del grafo. Añade conftest con la fixture
integration_client (env apuntando a agents/ y policies/ del repo, caches DI
limpiadas).
