Resolve "Upgrade Monitoring Setup Page, Add Question Management #37hg3wd"

Missing requirements

As we're going to be adding the functionality to edit questions in the next sprint, @MeBrei agreed that we don't need to reuse the old question edit modal for this issue. As such this issue has a very basic modal to edit the questions, and the key thing to test is that the questions are shared correctly via the QR code.
