WHY IT NEEDS A POLICY

Why mikrotik_add_blackhole_route needs a policy

This tool creates a new blackhole route on a MikroTik router, which silently drops traffic destined for specified networks. While it is reversible (routes can be removed), misuse could cause significant network disruption by blackholing legitimate traffic. It falls under Write as it creates a new routing entry, but has high severity due to potential for widespread connectivity loss.
