[Technical] Course disabled status in Backend

[DimitriB01]

Technical

Disabled courses should be defined in the backend through a timestamp (for example). Frontend fetches these informations. Additionally we need conditional rendering on the Frontend course and topic page, so that it does not render if the course is not active (when the user enters a manual url).
