refactor(dashboard): restructure dashboard components and improve data handling

- Moved dashboard components (Donut, Gauge, Sparkline) to their own files for better organization.
- Created a new DashboardHeader component to manage the header state and display service status.
- Introduced a layout component for the dashboard to encapsulate common layout styles.
- Simplified the Dashboard component by utilizing new components and reducing inline logic.
- Added type definitions for dashboard data in a new types.ts file.
- Enhanced the visual representation of data with improved SVG elements and accessibility attributes.
- Removed redundant code and improved overall readability and maintainability.
