Can't edit model. Model in config. Store model in db via `/m

Error message

Can't edit model. Model in config. Store model in db via `/model/new`. to edit.

What it means

Source-of-truth guard on model update: the model_id exists in the live router but has no DB row, meaning it was defined in config.yaml. Config-defined models are immutable via the API — they must be edited in config and reloaded, or migrated to the DB via /model/new.
