Improve debug logging with caller context in AcBinaryHubProtocol

Diagnostic logging methods now use [CallerMemberName] to pass the actual caller's name to the logger via EventId.Name, ensuring logs reflect the true call site. Log message formats were simplified by removing explicit class prefixes. Comments clarify the rationale, and all internal calls were updated to the new signatures.
