Returns the x402 PAYMENT-REQUIRED challenge for a locked quote so an x402-capable wallet client can sign it. No payment is taken at this step. Probes the canonical per-quote pay URL (/v1/quotes/:quoteId/pay). The preferred way to actually pay is for the wallet to perform the standard x402 in-band handshake against paymentUrl; this tool is for inspection or for the detached-signature flow via submit_paid_mail_job.
