Other information

[ArnaudFlaesch]

Thanks for the approval, there's still one test failing, I don't know why exactly. Might be worth it to replace Karma with Vitest as Karma is deprecated and Angular 21 has native support for Vitest.

[AdrisGithub]

The Test also fails on the current master Branch.

Would probably be smarter to just merge these Changes and then maybe switch to vitest in another PR.

[Masmarino]

It will be cool to merge quickly this PR if tests also fails on main branch yes.

The failing CI (npm ci) looks due to an out-of-sync package-lock.json.
