Switch wallet pass barcodes from QR to Code 128 format using the
card_number (digits only), so standard retail barcode scanners can
read loyalty cards. Apple Wallet keeps QR as fallback in barcodes
array. Also fix stale Vendor.loyalty_program relationship (now
company-based), add parent init calls in vendor JS components,
and update module docs to reflect Phase 2 completion.
