Dorian 07772b563f fix(companion): wallet scanner reads dense invoice QRs — 0.5.22 ...

Root cause (diagnosed live via CDP on a Pixel 9a): camera permission
granted and the native camera streamed (2m35s active) but ZXing returned
zero decodes for Lightning-invoice QRs — window.__archyQrResult received
0 calls. Dense BOLT11 codes need more pixels/module AND sharp focus; the
9a's main lens rests at a far focus and 1280x720 wasn't enough, so dense
invoices never resolved while sparse address QRs did. Fix: analysis at
1920x1080 + a repeating centre autofocus tick (a static hand-held QR
never retriggers continuous-AF on its own).
