feat(loyalty): fix Google Wallet integration and improve enrollment flow

- Fix Google Wallet class creation: add required issuerName field (merchant name),
  programLogo with default logo fallback, hexBackgroundColor default
- Add default loyalty logo assets (200px + 512px) for programs without custom logos
- Smart retry: skip retries on 400/401/403/404 client errors (not transient)
- Fix enrollment success page: use sessionStorage for wallet URLs instead of
  authenticated API call (self-enrolled customers have no session)
- Hide wallet section on success page when no wallet URLs available
- Wire up T&C modal on enrollment page with program.terms_text
- Add startup validation for Google/Apple Wallet configs in lifespan
- Add admin wallet status dashboard endpoint and UI (moved to service layer)
- Fix Apple Wallet push notifications with real APNs HTTP/2 implementation
- Fix docs: correct enrollment URLs (port, path segments, /v1 prefix)
- Fix test assertion: !loyalty-enroll! → !enrollment!
