Pull request overview

This PR fixes a visibility issue with ToolStripStatusLabel text in High Contrast mode when using System RenderMode. The fix ensures that text is properly highlighted against the background, making it readable for users who rely on high contrast accessibility features.

• Added highlight background rendering (FillRectangle) for pressed and selected states in high contrast mode
