SSR cockpit: label the response time, leave test reports out of the client error counts (0114-FE)

The big response time number is labelled last check. ClientErrorClassifier tells smoke and curl test reports and bot reports apart; tests are counted separately and left out of the tile, the hourly bars, the list and the dashboard tile, bots keep a label.

+ * endpoint smoke test. Bot: a crawler user agent (Googlebot & Co.); bot
