chamikaJ 78d960bf01 feat(gantt): introduce advanced Gantt chart components and demo page
- Added new components for an advanced Gantt chart, including AdvancedGanttChart, GanttGrid, DraggableTaskBar, and TimelineMarkers.
- Implemented a demo page (GanttDemoPage) to showcase the functionality of the new Gantt chart components.
- Enhanced project roadmap features with ProjectRoadmapGantt and related components for better project management visualization.
- Introduced sample data for testing and demonstration purposes, improving the user experience in the Gantt chart interface.
- Updated main routes to include the new Gantt demo page for easy access.
