The recipient input on /wallet's Send dialog now has a camera button
that opens a QR scanner. Bitcoin BIP-21 URIs are parsed and the
silent-payment fallback (?sp=) is preferred when present, falling
back to the on-chain address otherwise. Plain addresses, sp1… codes,
npub, and nprofile values are dropped into the input verbatim and
resolved by the existing recipient logic.
QrScannerDialog is a standalone component (ported from Ditto) that
owns the camera lifecycle via getUserMedia and the qr-scanner npm
package. It surfaces failure modes (insecure context, denied
permission, no camera, busy camera, overconstrained, ready timeout)
instead of a silent black screen, and offers a flash toggle when the
device supports it.
Android needed an explicit CAMERA permission in the manifest; iOS's
existing NSCameraUsageDescription string was extended to mention QR
scanning. No Capacitor camera plugin is required — the standard web
APIs work inside WKWebView and Android's WebView.
