Fix doubled top inset gap on Insights toolbar

The navigation-bar overlap fix in #558 added fitsSystemWindows="true"
to the Insights CoordinatorLayout. Because Insights uses the theme's
window-decor action bar (not an in-layout AppBarLayout), the status
bar inset was effectively counted twice and a large empty gap appeared
between the toolbar and the hero card.

Mirror the approach already used for Settings/Timeline in c50bea9:
drop fitsSystemWindows from the layout root and instead apply only
the bottom system-bar inset to the ScrollView so the original nav-bar
overlap fix still holds.
