MODELIX-721 Migrate cucumber tests for model-server to ktor tests

[mhuster23]

On my local machine the migrated test cases now only take 2s instead of 38s.
The saved 36s are roughly a 40% reduction of the previous total time to test the model-server.

Do we know the reasons for why some of the cucumber scenarios were commented out? Is it safe to drop them?

Apart from that, only minor things that I added.

After #862, kotest assertions would now also be available as an option.

Ah, good idea with the plugin.

The only thing potentially left is that we have the exact same logic now copied to two tests, which could be deduplicated.
