refactor(web): remove deprecated dashboard components and enhance KPI grid

- Deleted unused components: `DashboardActivityTimeline`, `DashboardFramePanel`, `DashboardModulesGrid`, `DashboardRecentJobsGrid`, and `DashboardRecentRevisionsGrid` to streamline the dashboard.
- Updated `DashboardKpiGrid` to improve KPI display logic, including progress indicators and enhanced badge functionality.
- Refactored `DashboardNetworkHealth` to provide better status representation based on loading states and network conditions.
- Introduced new properties for KPI cards to support progress tracking and improved visual feedback.

This cleanup aims to enhance performance and maintainability of the dashboard while providing a better user experience.
