feat(insights): mount Health Score panel in hero strip

The hero strip's right side, empty by design since B1, now paints the
<HealthScoreCard> when `analytics?.healthScore` is non-null. Layout
flips from `flex-col` to `flex-row` on `lg+` so the panel sits beside
the title block on desktop and stacks below on mobile.

The `onAskCoach` prop signature picks up an optional `prefill`
argument so the same handler powers both surfaces — the action-row
button passes nothing (drawer opens blank), the score panel passes
"Why is my health score X out of 100?". One drawer instance, one
state pair, one consistent UX.

Tests: 5 new hero-strip cases pin the score panel slot, the lg-row
layout switch, and the conditional ask-coach button mounting.
