fix(cli): use keyword args for fetch_nous_models (always TypeError)

fetch_nous_models() uses keyword-only parameters (the * separator in
its signature), but models.py called it with positional args and in
the wrong order (api_key first, base_url second). This always raised
TypeError, silently caught by except Exception: pass.

Result: Nous provider model list was completely broken — /model
autocomplete and provider_model_ids('nous') always fell back to the
static model catalog instead of fetching live models.
