Show transparent-mode (vWire) firewalls in path trace

NetBrain path trace currently does not display firewalls operating in Layer 1 virtual-wire (transparent) mode when they sit inline between paired Layer 3 devices, resulting in an incomplete path calculation that omits an actual traffic-inspection point. This enhancement would extend path trace logic to detect and include vWire-mode firewalls within the calculated path between L3 devices. Customers using inline transparent firewalls for traffic inspection would gain accurate end-to-end path visibility, improving troubleshooting confidence without needing manual verification of security device placement.
