What it does
This class handles saving shipping information (address and method) for guest checkout sessions.
It acts as a wrapper that converts the guest's masked cart ID into the actual quote ID, then delegates to the main shipping information management service.
Developers use this when implementing guest checkout APIs or customizing the guest shipping step.
