Why create_address_range needs a policy

Creating address ranges is a reversible write operation that modifies firewall configuration state. While it doesn't immediately cause destruction or execute commands, it creates objects that affect network security policies. Severity is high because misconfigured address ranges could disrupt network access or inadvertently permit/deny traffic to unintended targets.

From the tool's definition Tool name 'create_address_range' indicates creation of a network address range object. The FortiManager context involves 'firewall policy management' and 'network configuration', confirming this creates a network configuration entity.
