fix(flex): the Chase new panel's spot click zooms the panadapter too

Every other spot click — cluster grid, band map, watchlist, alert list — goes
through handleSpotClick, which applies the operator's per-mode panadapter
width after the tune. The Chase new panel had its own pick handler that tuned
and stopped there; it now makes the same view change, after the tune for the
same reason.
