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.

Since it's not clear if IRIs should be unique in the API (also with subclasses etc)
just stop usingn them for now, to avoid name ID clashes.

This reverts commit 6324718b.

This reverts commit 3716524b.

Just change all imports and dependencies.

port to firstName/familyName

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

We now enable it by default for everyone. The plan is to load the API
user instead and not the person as a next step. This api should work
even for users that don't have a person associated.

This removes the 'show-image' (false by default) and removes the functionality
to show a user profile image in the logout dropdown.

We've never used this actively and want to clean things up, so remove it.
