• Replace the actual accordion menu called 'Módulos' by a simple menu called 'Cursos'.
• The new 'Cursos' menu should take to the same list page created before but it should beave in a different way:

1. If the user already has the training bought should show a button to let access it.
2. if the user doesn't have the training bought, it should view a button to let buy the training.
