fix(insights): count failed fetches toward a bounded poll's ceiling

The status and advisor polls counted attempts on dataUpdateCount, which a
failed fetch does not move, while the last good payload stayed in place and
still said preparing. A request that kept failing polled an open page for
as long as it stayed open. Attempts now include the failed fetches.

The poll inventory moves from a comment into a guard held to every
refetchInterval in the tree; four polls were missing from the comment.
