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.

In case the activity emits this event then we switch to the specified activity.

This was forgotten ebcause it isn't used in the tests currently

This reverts commit 421d92f3.

In case the current state is the default one we don't redirect.
This gets rid of the initial redirect/histroy entry when loading the page.

If the current state can't be used to generate a path just fall back
to the current path

Use a dbp-rpovider in the app shell to use the attributes auth, requested-login-status and analytics-event only locally

This happens for example if we access "/dbp-signature.html" in which case the
router interprets the file name as a language.

Register the activity properly and create a scoped element if the API is there.

One all bugs are fixed upstream this should allow us to switch to lit v2
without any further changes.
