Correct protocol labeling in path trace policy-match results

NetBrain currently displays a protocol label in path trace denial results that does not accurately reflect the underlying evaluation logic. When IPv4 is selected without specifying a transport protocol, the path denial message states that the path was denied by a matched TCP/UDP policy, even though no specific transport protocol was actually evaluated or matched. This enhancement would correct the displayed wording to accurately represent the matching logic used, such as labeling the result as IP-based or indicating that any protocol is permitted when no specific transport protocol is selected. Accurate labeling would help customers correctly interpret path trace results and avoid misdiagnosing policy behavior during troubleshooting.
