feat(scanner): perspective warp card detection (Phase 2) (#158) 
Add quad corner refinement and homography warp for rectified identify
crops; wire warped capture through identifyTrackedCardCapture with
validation and axis-aligned fallback; add detection frame a11y labels.

Brief 2: Wire warped capture into identify + overlay a11y

Goal

Use perspective-corrected crops for L1/L2 identify; keep overlay on axis-aligned bounds; add live-region label on detection brackets.

Acceptance criteria

  • identifyTrackedCardCapture passes cardTracker.corners to capture
  • captureCardRegionFromVideo warps when corners present, else fallback
  • use-camera-scanner.js comment no longer claims OpenCV
  • DetectionFrame exposes role="status" + aria-label
