Subject: [PATCH] feat: add QR code generation script for seeded zones

Adds scripts/generate-qr.ts that generates one 400px PNG per warehouse
zone into public/qr/ (gitignored). Encodes /report?zone=<token> URL per
zone using NEXT_PUBLIC_APP_URL (default http://localhost:3000). Adds
public/qr/.gitkeep so the output directory is tracked. All 8 tests pass.
