feat: payment routes + ranked queue endpoint + app wiring

Add /api/payments router (connect-wallet, wallet-status, create-invoice,
check, submit-cashu, winnings, claim, disconnect-wallet). Add ranked
queue endpoints to /api/queue. Mount payments router in app.ts with
orphan payment recovery on startup.
