[Adrian-Moldovan]

The preview interface should be accessible from

1. the quiz list clicking a button
2. from the quiz edit form through the future implemented toolbar(containing list, new, preview)

The quiz will be loaded in a popup after requesting the API the content of the quiz. The response should provide all the questions and possible answers.( API endpoint: /api/admin/quizzes/{quizId}/questions/details)

The quiz controls will be displayed according to the API data.
