feat(metrics,web): Enhance dashboard with advanced metrics visualization

- Integrate Recharts library for interactive data visualization
- Add detailed latency distribution charts and error type analysis
- Implement bandwidth and performance metrics graphs
- Update metrics collection to support more granular statistical tracking
- Modify frontend API routes to remove /admin prefix
- Improve metrics display with responsive and informative charts
