UserStory #1959
<Changes>
1. Replaced CSV-based User serialization and deserialization with SerializedUser record-based serialization for shared memory storage.
2. Implemented User::serialize() to convert User objects into fixed-size SerializedUser structures containing user details and enum values.
3. Implemented User::deserialize() to reconstruct User objects directly from SerializedUser records.
4. Updated User class interfaces to use SerializedUser types instead of std::string serialization APIs.
5. Removed legacy CSV serialization support, including CSV parsing logic and header generation functionality.
6. Added SerializedUser dependencies through SerializedRecords.h inclusion and forward declaration support.
