Subject: [PATCH] fix(coinpayportal): add coin.chain fallback to
 coinToPaymentCurrency

CoinPay's /api/oauth/userinfo returns wallets as {address, chain: "SOL"} (not symbol). The symbol computation in coinToPaymentCurrency never checked coin.chain, so SOL wallets were never recognized and invoices failed with "Select a CoinPay receiving wallet" error.
