Include status of OAuth2 service in app and environment status

[nilsgstrabo]

The app "box" on the front page and the environment "boxes" on the application page aggregates statuses from components and secrets, and if something is not running correclty, an exclamation icon is shown:

This status is calculated from component replicas, and if any of them are not running correctly, a warning is shown.
The status does not include the OAuth2 service replica statuses, and if this one is failing, e.g. due to incorrect Redis password, there is no indication of a problem in the app list on the front page, or the app's environment page. This makes it hard to debug (follow the signs) for users have not correctly configured the OAuth2 service.

I suggest that we include the OAuth2 service status in the app "box" and environment "boxes". It would also be useful to show the OAuth2 replicas in the active component list, possibly suffixed with "(OAuth2)"

DoD

Errors with OAuth service aggregates to the top error icon/report
