AddressAdditionalDataInterface

What it does

This interface defines the contract for additional data that can be attached to quote addresses beyond standard fields.

Developers use this when they need to extend quote address functionality with custom data, such as delivery instructions, location details, or third-party integrations.

It provides extension attributes support, allowing modules to add custom fields without modifying core address structures.
