Pull Request Overview

This PR fixes an issue where columns inappropriately move to the adaptive row when row dragging is enabled in TreeList/DataGrid. The fix ensures that adaptive rows are properly hidden/shown during window resize operations when best-fit mode is toggled.

Key Changes:

• Added logic to hide adaptive rows during best-fit mode calculations to prevent interference with column width calculations
• Extended TreeList TestCafe model with methods to check adaptive button visibility
• Added TestCafe test to verify adaptive row behavior with row dragging enabled
