WHY IT NEEDS A POLICY

Why bulk_create_properties needs a policy

This tool creates multiple property records (up to 500 at once) in the system, which is a write operation. The blast radius is high because a miscall could flood the system with hundreds of duplicate or incorrect property listings, potentially causing significant data integrity issues across the rental management platform.
