Up until now it would throw and never set a login status. This would lead
to the login process never completing, and in our case the app-shell
would never show the app and only show a white page.

Instead set the status to logged out and show a notification.

It has new API which we want to use.

Newest Ubuntu switched Firefox to a snap, which breaks karma.

Try to use playwright to download and cache firefox/chromium
and use those for karma.

Compared to puppeteer where we did this some time ago this caches
the browsers globally, and only downloads them when we start the tests.

This reverts commit 6c632dc6

This reverts commit 6324718b.

This reverts commit 3716524b.

Just change all imports and dependencies.

Instead of throwing an error.

So the login process completes, but the user will not have any roles in that case.
This helps in case the API isn't set up but the user wants to try the frontend app.

We still want to finish the auth process in that case, so the app
can display some error message.

No longer needs babel, but requries an alpha version of the typescript plugin
for eslint 8 support

In case of the server template there are no enpoints registered by default,
but we still sue the keycloak login in the API docs. To avoid errors there
gracefully handle that case.
