Create a secure Stripe payment link for an Alt eSIM plan. Returns a payment URL the BUYER opens to pay (the agent never handles card details) AND a checkout_session_id. After the buyer pays, call get_qr_code with that checkout_session_id to fetch the eSIM QR and show it to the buyer. The QR is also emailed. Charged in USD. You MUST collect the buyer's real email.

Fetch the eSIM QR code(s) for an order, to show the buyer directly. Pass the checkout_session_id from create_checkout. Returns a clear `status`: 'awaiting_payment' (buyer has NOT paid — tell them to pay), 'processing' (paid, eSIM still provisioning — retry in ~30s), 'ready' (returns the QR image(s) + ICCID(s) to display), 'expired', 'refunded', or 'failed'. Use the status to tell the buyer exactly what's happening — never assume payment succeeded.
