- Simplified MetricsMiddleware by removing unnecessary comments and focusing on essential request logging. - Updated RequestLog structure to exclude the Referer field from JSON serialization, enhancing data privacy. - Removed top referers tracking and associated HTML/CSS elements to declutter the user interface and improve performance. - Cleaned up CSS styles related to referers for a more streamlined design.
