[ADD] awesome_owl: Add Card, TodoList, and Counter components

Introduced new Owl components in the awesome_owl module, including interactive
Cards, a dynamic TodoList with task management, and a reactive Counter. These
components demonstrate the usage of Owl's reactive framework and enhance the UI
with reusable and interactive widgets for frontend development in Odoo.
