Profiling/monitoring :Add interactive monitoring dashboard and integration tests for monitoring endpoints

Browse Source 
- Implemented an interactive monitoring dashboard in `demo_monitoring_dashboard.py` for real-time statistics, profiling session management, and system resource monitoring.
- Created a quick test script `test_monitoring_quick.py` to verify the functionality of monitoring endpoints.
- Developed comprehensive integration tests in `test_monitoring_endpoints.py` covering health checks, statistics, profiling sessions, and real-time streaming.
- Added error handling and user-friendly output for better usability in the dashboard.

- Real-time statistics with auto-refresh
- System resource monitoring (CPU, Memory, Disk)
- URL-specific performance metrics
- Profiling session management
- Interactive commands (view, create, delete sessions)
- Color-coded status indicators
**Dashboard Commands:**
- `[D]` - Dashboard view (default)
- `[S]` - Profiling sessions view
- `[U]` - URL statistics view
- `[R]` - Reset statistics
- `[N]` - Create new profiling session (from sessions view)
- `[V]` - View session details (from sessions view)
- `[X]` - Delete session (from sessions view)
- `[Q]` - Quit
