chore: update arc42 documentation

[ReneSchroederLJ]

Description

• updated Arc42 to better represent the current state of the application

Pre-review checks

Please ensure to do as many of the following checks as possible, before asking for committer review:

• DEPENDENCIES are up-to-date. Dash license tool. Committers can open IP issues for restricted libs.
• Copyright and license header are present on all affected files
• If helm chart has been changed, the chart version has been bumped to either next major, minor or patch level (compared to released chart).

Thanks a lot for the rigorous efforts! One thing to add a few things of taste (I would go for autoformatted tables) :)

[ReneSchroederLJ]

I've auto formatted the tables as requested.

While doing that I realized that the current configuration of the repo will auto format lists with an indentation of 4 which is quite unusual for markdown and causes markdownlint to complain. I added a rule for markdown files to the .editorconfig file to set the indentation to 2.

Now auto formatting is in line with typical markdown conventions.

Thanks for your update! Found one version mismatch I missed earlier. Please adjust and merge main to merge :)

LGTM, thanks a lot!
