#4275529 Offer Reset: custom post-purchase Thank You for Jetpack Security and Jetpack Complete [v2]

Changes proposed in this Pull Request

• Add post-purchase Thank You notes/modals for Jetpack Security Daily/Real-time and Jetpack Complete.

This is a fixed version of #45196.

Implementation notes

• Instead of relying on what it’s in the URL to get the purchased product, we inspect the current cart. If the cart doesn’t have a Jetpack product or plan, we use what was passed in the URL.
• I also added unit test to make sure getting the product from the cart works as expected in the cases we want it to.
• The ThankYou components have some repetition. We will fix that in a following PR.

Testing instructions

• Run this PR with the Offer Reset AB test enabled.
• Visit the Plans page and purchase any of the new plans.
• Verify that you see a Thank You note that represents the purchased product.
• Repeat the process with an old Jetpack product (Backup or Scan) and verify they still work as before.
