A missing first article is an inspection result, not a failure

Eweka answers 'no such article' after ~450 ms; a quarter of inspection
requests were for missing articles and each failed job was retried up
to three times. Files get content_type 'missing' instead; homelab also
records it from failure reports of nodes not rebuilt yet.
