WPB-26249 [Web/QA] Migrate from anta to QA federation env for federation tests

[markbrockhoff]

I triggered a CI run for your branch: https://github.com/wireapp/wire-webapp/actions/runs/27529455602/job/81363978580

There are some failures due to call instability, but those are not affected by your changes. However inside onPremLoginRedirect-TC-8757.spec.ts it looks like the url of the federation environment was hardcoded which is causing it to fail now. Could you please also fix that? Ideally by making the function claimDomain on the brig api client accept the domains for the backend to federate as parameter. This way it will be more transparent where they are actually used. :)
