feat: add new dashboard components and enhance UI

- Introduced new CSS variables for light theme in `globals.css` to improve visual consistency.
- Replaced `Card` component with `StatCard`, `ProgressBar`, and `MetricCard` in `DashboardStats`, `ProductivityAnalytics`, and `RecentTasks` for better modularity and reusability.
- Updated `QuickActions` to use `ActionCard` for a more cohesive design.
- Enhanced `Badge` and `Button` components with new variants for improved styling options.
- Added new UI showcase section in `UIShowcaseClient` to demonstrate the new dashboard components.
