LLMClientFetchSettingsFromServerAsync Method

Reads the server's active settings (GET /api-keys + GET /session) and updates Config with non-secret fields: models, endpoints, backend, flags. API keys in Config are NOT overwritten (server returns masked values). Call this whenever the user may have changed settings via the web UI.
