/**
 * Adds two visitors created via the new "Manual entry" toggle on the
 * Add Visitor page. Manual entries skip the check-in policy entirely:
 *   - requiresApproval = false
 *   - assignedApproverId = null
 *   - status stays EXPECTED (no approval awaited)
 * QR/shortId are still generated so the row is shape-compatible with
 * existing tooling, but reception won't surface or scan them.
 *
 * Run with: npx ts-node -r dotenv/config src/scripts/manualEntries.ts
