build: check format & lint in GitHub workflow

[SchroederSteffen]

Description

While preparing another change, I noticed that the lint script doesn't work and that there formatting issues in the code.
Both could be detected if the GitHub workflow test would also lint & check the formatting.
This is added by this PR.

I also added a verify script to be able to easily execute all relevant scripts locally.

To get the build green, we also need to format the code in this PR. I'd suggest to extract these formatting changes into another PR which should be merged before this one (#670).

Additional context

The current lint script eslint '{src,apps,libs,test}/**/*.ts' runs into the following error:

> eslint '{src,apps,libs,test}/**/*.ts'

Oops! Something went wrong! :(

ESLint: 8.49.0

No files matching the pattern "'{src,apps,libs,test}/**/*.ts'" were found.
Please check for typing mistakes in the pattern.
