WHY IT NEEDS A POLICY

Why mikrotik_expand_ip_pool needs a policy

This tool creates or modifies network infrastructure configuration reversibly. While it does not delete data or move money, it alters DHCP/IP allocation ranges which affects network operations.

From the tool's definition mikrotik_expand_ip_pool expands an existing IP pool by adding more ranges, which modifies network configuration state on a MikroTik RouterOS device. This is a creation/modification operation (adding new IP ranges to an existing pool).
