add_to_cart

Add placed marketplace items to the shopping cart through the same store action as the UI, one line per instance at the current catalog price. Any unknown instance, pre-existing (non-marketplace) item, instance already in the cart, or missing product rejects the whole request with per-instance reasons and leaves the cart untouched. Returns cart status, each line (id, product, quantity, unit price, instance id), the cart total, and how many lines were added.
