Major changes:
- Removed C++/CLI layer from server side (MtApiService). Server side is written by C++ only. It is packed only in one DLL without using GAC as previous version.
- Migrated from WCF to WebSocket for communication between server and client side.
- Using JSON messages as communication objects between client and server side.
- Added sync functions connect/disconnect in client side (C#).
- Migrated client side to .Net 8.
