Switch to binary serialization, update compression to GZip

- Changed default SignalR message serialization from JSON to binary.
- Updated AcSerializerType enum values: Binary=0, Json=1.
- Disabled string caching when intern table is present.
- Replaced Brotli with GZip for JSON compression in comments and logic.
- Refactored SignalResponseDataMessage deserialization for improved error handling.
