refactor(v5): remove CLI-specific fields and labels from clusters UI

Remove server count badge, last run status, and CLI summary from the
cluster detail panel. Rename "CLI state" to "Cluster state" and update
the add-server dialog to drop "CLI-generated" wording. Add test
assertions covering all removed and renamed elements.
