[IMP] point_of_sale: load default demo data

When loading the pos without demo data, before we had a wizard that allowed the user to load data before the pos starts.
Now, we let the user go to the frontend without preloading products and categories in the database.
In the front end, when no products and categories are loaded, we let the user press buttons to load the default products and categories.

The user can also be redirected to the back end to add new products.
