TTS Import Model Documentation

1. Purpose

This module provides the data model layer for TTS (Toyota Test Setup) import functionality within the DataPRO test setup system. It contains model classes representing test configurations, channel records, hardware channel assignments, level triggers, and various summary records. These models implement INotifyPropertyChanged for WPF data binding, support serialization via GetBytes() methods for hash generation, and serve as the bridge between hardware abstraction layers and the UI for test setup import workflows.
