ChannelCodesListView Documentation

1. Purpose

This module is a WPF code-behind view component for managing channel codes within the system. It provides the interaction logic for ChannelCodesListView.xaml, handling user interactions for two distinct lists: ISO channel codes and User-defined channel codes. The view supports filtering, sorting, selection tracking, and modification marking, delegating all business logic to an IChannelCodesListViewModel via data binding.
