Implement initial Layout

[hendrikebbers]

We have a first version of the design: https://www.figma.com/file/nBPzHwYBthcb37IHVVqzg3/Tailwind-UI---App?type=design&node-id=426-1600&mode=design&t=yQwDEaftArhOwTDY-0

The design can be implemented as a static page based on Tailwind in the first step.
At the end I currently think that a react based approach would be the best for us. @Subtain-Farooq can you use react?

@Subtain-Farooq we now have a folder to implement the frontend: https://github.com/OpenElements/BenchScape/tree/main/jmh-frontend/src/main/frontend
