- Added reusable `serializeCards` function for card list serialization. - Enhanced `DrawCardPayload` with a `cards` field. - Introduced `serializeMessageStatus` and `deserializeMessageStatus` for message status handling. - Updated deserialization logic to validate and include `status_code` field. - Improved error messaging and validation for payload deserialization methods.
