Pull request overview
This PR extends the AlternateColor functionality for ListViewBase to support scenarios where no item container is used. When an item container is unavailable, the extension now falls back to using the item itself if it's a Control.
Key changes:
- Added fallback logic to use the item as a Control when ItemContainer is unavailable
- Refactored code across multiple ListViewExtensions files for consistency and modern C# patterns
- Consolidated event cleanup logic with uniquely named unload handlers
