Extract Ladill QR Plus as standalone app at qr.ladill.com.

Utility QR types only (URL, WiFi, link list, business, app download) with SSO, Billing API integration, public /q resolver, and qr-plus:import for platform migration. vCard and commerce types stay on the platform. Co-authored-by: Cursor <cursoragent@cursor.com>
