feat: a lot

i did a lot of work, and i also forgot to add commits regularly. I added the controller routes to create and delete controllers, improved error handling und improved the authentification process. I'm gonna add an websocket next and then I should be hopefully done with the foundations of this project. I may also add anviewControllers route which respons with every available controller
