Align jest sample tests with the proven jest-selenium flow

Mirror the known-working load-testing-backend/sample/jest-selenium scripts:
- add-to-cart: wait for elements to be visible before reading text (fixes
  the empty cart-title race the reviewer hit), use the short descendant
  selector, beforeAll/afterAll session.
- checkout: wait for the cart overlay to open before closing, route the
  tail through Continue Shopping -> Orders, wrap interactions in
  located/visible/enabled waits.
