Drop the InsightAdvisorCard component, its four integration tests
under src/components/insights/__tests__, the page-level mount on
/insights, the orphan i18n keys (advisorTitle, aiOverviewTitle), the
e2e advisor-card spec, the dashboard.spec.ts advisor assertion and
every related comment. The InsightsTabStrip regenerate icon stays
untouched as the sole power-user refresh affordance. The iOS-consumed
POST /api/insights/generate endpoint and its request/response shape
stay byte-stable.
