[IMP] awesome_dashboard: make dashboard items dynamic and reusable

This commit restructures the dashboard to render items dynamically based on a
centralized configuration list. This approach enables easier extension and
reuse of dashboard item types, improving maintainability and scalability.

Key changes include:

Introduction of dashboard_items.js to define a list of item configurations,
including type, title, and props. This enables dynamic rendering of
dashboard widgets like NumberCard and PieChartCard.

The DashboardItem component now acts as a dynamic wrapper that loads and
renders the appropriate child component based on its type. This is achieved
using Owl's dynamic component syntax and t-component.

Separation of each card type into its own file (NumberCard, PieChartCard)
to promote single-responsibility design and reuse across modules.

All components continue to use Bootstrap utility classes and maintain
responsive, clean, and modern styling.

This change lays the foundation for a fully extensible dashboard architecture,
where new visualizations can be added without modifying the core dashboard view.
