feat(web): enhance overview page with improved state management and UI components

- Refactored state management for modules, revisions, peers, speakers, and jobs, enhancing loading and error handling.
- Updated imports to utilize core UI components for better maintainability and consistency.
- Introduced derived states for KPI cards, providing real-time insights into system metrics.
- Improved loading function to fetch data efficiently and handle errors gracefully.
- Enhanced UI layout with new icons and dynamic descriptions based on last updated timestamps.
