feat: redesign payment targets modal with QR, copy and pay buttons

Each target now renders in a single row with the payment method and
address on the left and three trailing icon buttons: QR (opens a dialog
showing the raw address as a QR code), Copy (clipboard + toast), and
Pay (existing payto:// intent). Adds QrCode2 to MaterialSymbols.
