Summary

• Add the subscription selector, plan selection, and terms dialog as a ReactEdge widget.
• Dispatch reactedge:subscription:submit with the selected plan and product context so the storefront host can handle Magento cart work.
• Keep subscription persistence, checkout, payment, and idempotency outside the widget.
