/**
 * Security & Multi-Tenant Isolation Tests for Real Estate API Routes
 *
 * Covers:
 *  1. Authentication enforcement (401 when unauthenticated)
 *  2. User-not-found handling (404 when email valid but no DB record)
 *  3. Organization / tenant isolation (userId always in where clause)
 *  4. Input sanitization (HTML/XSS escaping)
