fix: admin UI review round 1 (S47) - Art labels, usage only on success, result fallback

- Art column: only lit/media-delete and lit/divi-delete say "löscht",
  lit/post-trash "Papierkorb", other destructive tools "überschreibt".
- ConnectionUsage records only responses with status < 400 (mcp-oauth answers
  auth failures with WP_REST_Response 401, not WP_Error).
- Log result column: translated "unbekannt" instead of the raw value.
