feat: confirmation-aware TX verification (10-conf threshold)

Browse Source 
- 0-9 confs: show amber 'Pending/N/10' stamp on QR, auto-poll every 60s
- ≥10 confs: show green 'Paid' stamp (Monero standard lock)
- verify.php: store status ('pending'|'paid'), allow upward updates
- i18n: add status_pending + proof_confirmed_pending (all 7 langs)
- style.css: add .proof-result.warning, .pending-stamp, .qr-container.confirming
- Polling stops on resetForm; short-URL viewers also poll verify.php
