/**
 * Smoke test for the quote-item insights backfill.
 *
 * What it does
 * ────────────
 * 1. Captures the existing `ai_item_insights` blob (so we can restore).
 * 2. Calls `populateQuoteItemInsights` on the target id, write=true.
 * 3. Re-reads the row and prints the new blob.
 * 4. Restores the original blob (best-effort) so the test is non-destructive.
 *
 * Run with:
 *   npx tsx scripts/smoke/populate-quote-item-insights.ts
 *
 * Requires .env.local with NEXT_PUBLIC_POCKETBASE_URL, PB_ADMIN_EMAIL,
 * PB_ADMIN_PASSWORD.
