/**
 * TEC-2932 — Duplicate detection e2e.
 *
 * Covers:
 *  - Same agent posting twice at the same coords + address → HTTP 409
 *  - Admin-only `GET /listings/duplicates` route gates (401/403)
 *
 * Full admin happy path requires a seeded admin login (see admin.spec.ts
 * pattern), so we only assert the auth gate at the e2e layer.
