Fraud Protection: Add Blackbox JS script loading (#63116)
* Add Blackbox JS script loading for fraud protection
Load the Blackbox JS telemetry SDK on checkout, pay-for-order, and
add-payment-method pages when fraud protection is enabled. A small
init script calls Blackbox.configure() with the site's API key and
Jetpack blog_id. Skips loading if blog_id is unavailable.
