Improves the dashboard with additional metrics and visualizations to provide a more comprehensive overview of application usage and performance. Adds new charts, including: - Word cloud for category analysis - Geographic map for user distribution (simulated data) - Response time distribution chart Refactors existing components for improved clarity and reusability, including the introduction of a generic `MetricCard` component. Improves error handling and user feedback during data refresh and session loading. Adds recommended VSCode extensions for ESLint and Prettier.
