Toggle to remove radiobuttons from List-component

### Description

The list component has a great setup to display dynamic data, but there should be a posiibility to remove the radiobuttons when selectedItem is unnecessary making the list component readOnly and non-interactible.

The whole column for the radio buttons should be removed, letting the specified colums fill the width of the list component.
Adding an optional field "selectableItems": false would solve this issue.

### Additional Information

_No response_

Start at the List-component entry point and trace how selectedItem controls the radio-button column. Add the optional selectableItems setting and verify that disabling it removes the radio-button column while allowing the remaining columns to use the available width.
