Add QR scanner to the send page (lazy-loaded decoder)
Scan a Bitcoin address, a BIP21 URI (fills address + amount), or a
signed-transaction QR (opens a broadcast confirmation, then relays it)
from a viewfinder button on the Send form.
Decoder strategy keeps the main bundle small:
- Prefer the native BarcodeDetector (Chrome desktop/Android) — no lib.
- Otherwise lazy-load jsQR from a separate dist/jsqr.js, only when the
scanner is opened. jsQR stays out of index.html (~424 KB vs ~551 KB)
and off the initial load.
- The service worker precaches jsqr.js so offline scanning works for
installed PWAs on browsers without BarcodeDetector.
The scanner needs a camera + secure context, so it never shows on a
standalone file:// page; offline air-gapped signing is unaffected.
