refactor: Restructure Performance Profiler and Dashboard Integration

- Updated file paths for performance-related headers to reflect new directory structure under `app/gfx/performance/`.
- Introduced new `PerformanceDashboard` and `PerformanceProfiler` classes for comprehensive performance monitoring and reporting.
- Enhanced performance metrics collection and visualization capabilities, including real-time updates and detailed reports.
- Improved memory usage tracking and optimization status analysis within the graphics system.
- Ensured compatibility with existing components by updating include directives across multiple files.
