payPay for an MPP purchase using the owner's saved card. The owner approves spending constraints once — the agent can then pay within those bounds instantly. You MUST pass the 'challenge' object you received from the merchant's shop.buy capability (the full challenge object from the payment_required response). Returns a 'credential' string — pass it to the merchant's shop.buy capability to complete the purchase.
