What it does
This class manages billing address operations for shopping cart quotes in Magento 2.
Developers use it to assign a billing address to a cart (optionally using it for shipping too) or retrieve the current billing address.
It handles validation, persistence, and thread-safe operations through mutex locking to prevent race conditions during checkout.
