Stop calling DNA a Pair enabler

DNA only fires on the round's first hand and only for a single played
card (dump/card.lua:3956) - sacrificing a full hand to enable the
easiest hand in the game is not a synergy. Its trips/quads enabling
stays; that is what the one-copy-per-round loop actually builds toward.
