Split armarest into backend and frontend

name: 🚀 Feature Request
about: Split armarest into backend and frontend

Is your feature request related to a problem? Please describe.

Should be separate for better code quality and Axii installs it anyways.

Describe the solution you'd like

Move backend and frontend folder into two separate repos and have a look at the shared files. Put them either into backend or frontend or into the Axii module for armarest.
