/**
 * Insights generation flow — `/settings/ai` exposes a "Regenerate
 * insights" button that POSTs `/api/insights/generate` and re-renders
 * the AI-generated text in the surrounding cards.
 *
 * The real endpoint hits an AI provider (OpenAI / Codex) which we can't
 * call from CI. We mock it with the schema documented in
 * `src/app/api/insights/generate/route.ts`:
 *
 *   { data: { insights: { changed, stable, drivers, nextSteps,
 *     confidence, limitations }, cached: false }, error: null }
 *
 * We then confirm the success message lands AND a query invalidation
 * fires on the insight-fetching endpoints (we re-mock those to assert
 * they're touched after the regenerate call).
