"""Chatbot wiring for the medical RAG API.

Root Cause vs Logic: startup failed because this layer passed an `api_key` argument into `AzureLLMClient`, but the shared Azure client already reads `FOUNDRY_API_KEY` / `FOUNDRY_ENDPOINT` from the environment. Keep auth configuration centralized in the client and only pass runtime behavior options from the chatbot layer.
