checkout.place_order

Turn a completed cart into an order — atomically reserves stock, freezes totalizers, creates the order (pending_payment). The order CONSUMES the cart lines; the cart itself survives with its buyer, address and preferences, ready for another purchase (one cart, many orders). Idempotent: repeating this call on the same cart while it is still empty returns the SAME order_id instead of creating a second one.
