fix(plex): a reshuffle survives a refresh landing mid-deal; the ↻ spins for a deal only

The ↻ intent was spent as its fetch set out, so a watched toggle's resync cancelling that fetch re-ran it as a re-read of the old draw. It now lasts until the latest deal answers. The button spun on every re-read of the same titles; it now follows the deal. Comments that said the Surprise draw is never refetched are brought in line.
