Pull Request Overview

This PR implements generic helper functions for wrapping and unwrapping arbitrary data objects using AES-GCM encryption. The implementation provides a client-side API for encrypting/decrypting data with server-managed keys.

Key changes:

• Added wh_Client_DataWrap and wh_Client_DataUnwrap functions for generic data wrapping operations
• Moved AES-GCM constants from implementation file to common header for reusability
• Added comprehensive test coverage for the new data wrap/unwrap functionality

@AlexLanzano overall, do a full pass of all keywrap AND datawrap handling functions and ensure the server never returns error back to the server processing loop unless it is a true internal server error that should cause the server to crash due to being in some indeterminate state. Otherwise, all client-induced errors MUST be propagated back to the client. I fixed a few already on you branch but there are more.
