Confirmed the client-side completeness metric works end-to-end (mediawiki_WikiLambda_aw_preview_reader_outcome_total is queryable on Grafana now).

However:

  1. this is only enabled on test wiki; we should start to expand into real wiki
  2. hasIncompleteSection() only checks data-pending, not data-failed/data-stale. E.g. test.wikipedia.org/wiki/Paris,_France shows data-stale="9" but got reported as complete. I'll add data-failed since reader isn't seeing valid content.
