Enhances dashboard with new metrics and charts

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.
