Pull request overview

This PR refactors authentication and metadata handling for gRPC requests in the C++ SDK. It introduces a new TAuthenticationError exception type to distinguish authentication failures from general contract violations, and consolidates duplicate metadata creation logic into a centralized MakeCallMeta method. The PR also adds support for OpenTelemetry trace context propagation via the TraceParent field.

Key changes:

• Introduced TAuthenticationError exception class for authentication-specific errors
• Refactored duplicated metadata creation logic into TGRpcConnectionsImpl::MakeCallMeta()
• Added TraceParent field to TRpcRequestSettings for OpenTelemetry trace context support

[Copilot]

The catch block for TAuthenticationError at lines 25-26 is redundant. It catches the exception only to immediately rethrow it unchanged. This block can be removed since the exception will naturally propagate without it, simplifying the code.

Suggested change

	} catch (const TAuthenticationError& e) {
	throw e;
