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 1: Quad corner detection + perspective warp

Goal

Replace axis-only Sobel box hunt with four-corner refinement and a homography warp helper that produces rectified card JPEGs.

Acceptance criteria

  • lib/scanner-card-warp.js exports orderQuadCorners, computeHomography, warpCardCaptureFromVideo
  • detectCardShapesFromFrame returns corners in video space
  • Tracker merge preserves corners on tracked cards
  • Unit tests for warp math + corner refinement
