test(fraud-protection): cover protected-gateway-available reCAPTCHA enqueue cases

Adds regression coverage for the previous commit: reCAPTCHA still enqueues when a
protected gateway (ACDC) is available at checkout despite the smart-button location
being disabled, still skips when no protected gateway is available either, and still
enqueues on the My Account "Add payment method" page when one is available there.
