Settle a failed Discover decision on the deck's newest read

A failed decision still waits for the deck read it makes itself, but no
longer carries that read's answer on its error. Whether its Side quest is
still pending is now asked of the deck query's newest successful read
(stillPending), both when the decision settles and when the page offers
Retry. A read that lands later and has the Side quest decided keeps it off
the deck and withdraws the Retry; a deck whose latest read failed offers no
Retry.
