1-3121: fix wrong counting for unhealthy flags (#8772)

This PR fixes the counting of unhealthy flags for the project status
page. The issue was that we were looking for `archived = false`, but we
don't set that flag in the db anymore. Instead, we set the `archived_at`
date, which should be null if the flag is unarchived.
