Post-purchase extension development without Chrome extension

The shopify app dev command now supports post-purchase checkout extensions without requiring the deprecated Chrome extension. This enhancement simplifies development, aligning it more closely with other checkout UI extension patterns.

Now, when you run shopify app dev with a post-purchase extension, the CLI will:

• Automatically configure cart permalinks with the necessary parameters for testing.
• Allow direct testing through the checkout flow without a browser extension.
• Redirect to the post-purchase page after the "Pay now" button is clicked.
