fix(tn-manager): Round 15 - Fix field name and type assertion errors

Fixed the final 4 compilation errors in TN Manager:

1. enhanced_types.go (3 errors):
   - Fixed endpoint.NodeID → endpoint.NodeName in GetSliceVXLANConfigs
   - Fixed endpoint.NodeID → endpoint.NodeName in GetSliceQoSStrategies
   - Fixed endpoint.NodeID → endpoint.NodeName in GetSlicesUsingNode

   The embedded tnv1alpha1.Endpoint struct uses "NodeName" not "NodeID"
   as defined in tn/manager/api/v1alpha1/tnslice_types.go

2. qos_manager.go (1 error):
   - Removed invalid type assertion on queue.BurstSize
   - BurstSize is already string type in QueueConfig struct
   - Changed from: if currentBurst, ok := queue.BurstSize.(string); ok
   - Changed to: if queue.BurstSize != ""

All TN Manager code now compiles successfully. Ready for integration testing.

Resolves: All tn-integration compilation errors
