Clearer terminal text selection

What's Changed

• Brightened the default dark terminal selection with an explicit blue overlay so selected text remains visible over transparent backgrounds.
• Preserved UI and terminal transparency settings; custom selection colors can retain their alpha channel in the color scheme editor.
