fix: Round 6+7 - Remove unused code and implement TN Manager methods

Round 6: Code cleanup (3 fixes)
- Remove unused appsv1 import from monitoring_chaos_test.go
- Fix unused testQuery variable in monitoring_e2e_test.go
- Fix iperf_test indexing: use server.Port instead of server["port"]

Round 7: Implement TN Manager methods (11 fixes)
- Add ConfigureVXLAN, ConfigureQoS, DiscoverNode to TNAgentClient (client.go)
- Add UpdateVXLANConfig, GetVXLANConfig methods to NetworkState (enhanced_types.go)
- Add UpdateQoSStrategy, GetQoSStrategy methods to NetworkState (enhanced_types.go)
- Add UpdateTopology method to NetworkState (enhanced_types.go)
- Add NewNetworkTopology factory function (enhanced_types.go)
- Fix type conversion from []TNEndpoint to []tnv1alpha1.Endpoint (enhanced_manager.go)
- Add fmt import to enhanced_types.go for error messages

All methods include proper error handling and logging via security.SafeLogf.
TN Manager methods are currently stub implementations with TODO comments
for future HTTP API integration.
