Pull Request Overview

This PR improves the visibility of selected DataGridView text in dark mode by conditionally setting the SelectionForeColor based on the dark mode state. The change ensures that selected text remains readable when dark mode is enabled.

Key changes:

• Modified the DefaultDefaultCellStyle property to use conditional logic for SelectionForeColor
• Added dark mode detection using Application.IsDarkModeEnabled
• Applied appropriate pragma warnings for the experimental API
