GuestBillingAddressManagement

What it does

This class manages billing addresses for guest shopping carts (non-logged-in customers) in Magento 2.

It acts as a wrapper that converts masked cart IDs (used for guest carts) into actual quote IDs before delegating billing address operations to the standard billing address management service.

Developers use this when implementing checkout functionality for guest customers to assign or retrieve billing addresses.
