Refactor SignalR protocol type resolution logic
Removed SignalParams.SignalDataType and migrated type resolution to protocol headers using new WriteHeader/ReadHeader extensibility hooks. AyCodeBinaryHubProtocol now writes and reads the concrete data argument type in the message header, enabling correct deserialization of object-typed arguments. Updated AcBinaryHubProtocol to support header context and made relevant helpers protected. Cleaned up legacy SignalDataType logic and improved documentation.
Full SignalR client→hub→service test infrastructure with testable components that bypass real network connections.
