feat(tests): Update tests for summary-free indexing

 The `llm` parameter is supplied per-document by
-`app.services.llm_service.get_user_long_context_llm`. We patch THAT
+`app.services.llm_service.get_agent_llm`. We patch THAT
 function to return a langchain-native FakeListChatModel so the rest of
 the chain works unchanged. No real LLM provider package is touched.
 
 Run-backend / run-celery use unittest.mock.patch.start() to install
 this at every binding site (the source module + every consumer that
-did `from app.services.llm_service import get_user_long_context_llm`
+did `from app.services.llm_service import get_agent_llm`
