Create cypres test for full round trip (webtop &wrongsecrets)

We need to build cypress tests that check based on a Minikube env whether:

• creating a team works: you can register a team, and then end up with having 2 buttons, that you can click to see the webtop and the wrongsecrets instance
• joining a team works: you can join the same team as in the previous test again by giving the passscode and that end up with having 2 buttons, that you can click to see the webtop and the wrongsecrets instance
• admin interface works
