fix: Remove hardcoded colors in disk health detection dialog for theme compatibility

- Remove hardcoded DPalette definitions (palette1-6) in DiskHealthDetectionDialog
- Remove all setPalette() calls that prevented theme color following
- Use option.palette.color(QPalette::Text) in DiskHealthDetectionDelegate for dynamic theme color
- Preserve semantic colors for health status indicators (good/damaged/unknown)

Log: Fix disk health panel font color not following dark mode theme
