ResourceServer now defaults to using TraceLogger if no logger is provided and properly awaits FetchBlobConfig. FetchBlobConfig is refactored to return a Task and handle missing configuration more gracefully. TraceLogger now writes logs to a file named after its namespace and sets up a TextWriterTraceListener for persistent logging.
Introduced ICompatibleLogger interface and TraceLogger implementation to enable flexible logging. ResourceServer now uses ICompatibleLogger for error reporting instead of Trace, improving testability and future extensibility. Updated project file to include new logger classes.
