Push a product from the authoring environment to production. This exports the product's
complete structure and imports it into the corresponding product on the production server.

The push operation:

1. Exports the product as JSON (same structure as the export endpoint)
2. Sends the JSON to the production server's import endpoint
3. Returns the import result from the production server

Requirements:

• The product must exist on both the authoring and production servers

Note: This endpoint is only available on the authoring server. Calling it from any other environment will return a 403 error.
