Fix log accordion colors for dark theme compatibility

- Replace hardcoded colors with UIManager system colors
- Add isDarkTheme() method to detect dark/light themes
- Set TextArea background, foreground, and caret colors from system
- Adjust header background based on theme (brighter for dark, darker for light)
- Ensure Label foreground uses system text color

Fixes white-on-white text issue on Gnome dark themes.
