FE-xxx: feat: build Stellar payment instructions UI — address, memo QR, countdown, and auto-confirm

[BigBen-7]

Description

After a ticket purchase creates an order, the backend returns { destinationAddress, memo, amountXLM }. There is no frontend UI for this Stellar payment flow — users have no idea what to do after clicking "Purchase".

What to do

Create src/features/orders/components/StellarPaymentInstructions.tsx:

• Destination address: display truncated + full on hover, one-click copy button
• Memo: displayed in red with a prominent warning — "Required — your payment will fail without the memo"
• Amount: XLM amount with copy button
• QR code: generate a web+stellar:pay?destination=G...&amount=X&memo=Y QR code using qrcode.react
• Countdown timer: shows time remaining before order expires (default 15 minutes)
• Auto-confirm: poll GET /api/orders/:id every 5 seconds — when status === "PAID", redirect to /tickets with a success toast "🎉 Tickets issued! Check your email."
• Expiry: when countdown hits 0 show an expired state with a "Retry Payment" button calling POST /api/orders/:id/retry-payment

Files touched

• src/features/orders/components/StellarPaymentInstructions.tsx (new)
• src/hooks/useOrderStatus.ts (new — polling hook)
• package.json (add qrcode.react)

PR requirement

• Closes #[issue_id] — Timeframe: 72 hours

/attempt #371

I will work on this scoped frontend payment-instructions flow: add the Stellar payment instructions component, a focused order-status polling hook, QR generation via qrcode.react, copy actions, expiry/retry handling, and redirect/toast on PAID status. I will keep the change limited to the requested files/package dependency and validate with the repo's lint/tests or build before opening the PR.

Competitor/status refresh after the newer PR #399 opened for the same issue:
#399

My earlier completed submission remains PR #397:
#397

Current contributor-side status rechecked now:

• PR feat: add Stellar payment instructions #397 is open, non-draft, and GitHub reports it as mergeable.
• PR feat: add Stellar payment instructions #397 includes the requested StellarPaymentInstructions component, useOrderStatus polling hook, qrcode.react, countdown/expiry/retry handling, copy controls, PAID redirect/toast, and focused tests.
• Validation already recorded on PR feat: add Stellar payment instructions #397: npm run lint, npm test, and npm run build passed.
• The newer PR Implemented the qr payment #399 currently has a failing Frontend CI / build-and-check (18.x) check and its changed-file list only shows src/hooks/payment.ts, so it does not appear to cover the requested component/files for FE-xxx: feat: build Stellar payment instructions UI — address, memo QR, countdown, and auto-confirm #371 yet.

No maintainer-requested changes are pending from my side. PR #397 is ready for review, and I can respond quickly if you want any adjustment.
