fix(story-mode): a second opinion in front of helpers neither splits them nor counts as one

Since second opinions ride on the next panel, an advisor call sorted to
the front of a helper panel tripped the old rule that kept advisor
panels apart, so "advisor, helper A, helper B" drew two helper panels,
and the first counted the advisor as a helper ("Claude calls in 2
helpers" for one helper). The rule has no job left and is gone; a
riding second opinion is never counted as a helper. One recorded page
changes: "Claude sends 1 helper off to work in the background."
