One-Box Startpage

The idea of the one-box interface is to only have the box "Similar Entities" on the start page and offer the other features like "Embeddings" on a second page as an extended version. The first page should only offer embeddings with a link "more", which would take one to the current starting page.

Further adjustments:
- Under the box there should text stating how many embeddings we currently offer. "xxx embeddings and counting" should be the text.
- The DICE logo should be at the top right corner (Having the logo at the bottom means it is not seen by all.)
- Adjustment of Text: "Our experts are continuously working on updates, we try to hide them in the news." ==> Why hide? It should be "you can find them in the news"
