scp80: keep the card preset selected after a send (v2.1.18)

cardsSave() calls cardsRebuildSelect(), and the innerHTML rebuild reset the
dropdown to its first option ("- Select card -"). Since the counter sync
saves after every send, the selection was lost each time and had to be
re-picked manually. The rebuild now restores the previous selection
(guarded by the preset still existing). Service worker v155.
