fix(insights): normalize stat-strip and target panel header rhythm

The stat-strip and target-summary panels were bare card-styled divs with
a flat space-y gap, so their tile header sat at a different offset from
the Card-wrapped tiles (assessment, mood, medication) on the same subpage
spine. Wrap both in Card / CardHeader pb-2 / CardContent so the
header-to-body offset matches. All content and data-slots are preserved;
the panel semantics ride on role + aria-label.
