Remove a custom agent cost item
Close the custom item as of now. The row stays so calls already priced with it stay explainable; calls on that (provider, item) from now on price at the catch-all fallback, which for an item nothing else names means unpriced. item_id is the custom_item_id the catalog carries. An id that belongs to a negotiated override rather than a custom item is a 404 — the two share an id space and each closes only through the endpoint that owns it.
