feat: Update .gitignore and enhance routing-related classes

- Updated `.gitignore` to include additional files and directories.
- Added summary comments and new properties in `LevelControlListItem.cs` for better clarity and functionality.
- Enhanced documentation in `SourceListItem.cs` and introduced new properties, including `Destinations` and a `ToString` method.
- Introduced `SourceRouteListItem` class with routing properties and expanded `eSourceListItemDestinationTypes` enum.
- Added `IRoutingSinkWithInputPort` interface in `IRoutingSink.cs` to support input port functionality.
