fix: Make safety features section much more subtle in help modal

- Replace bright yellow with muted background colors
- Use standard text colors (text-foreground, text-muted-foreground)
- Maintains warning icon but with consistent styling
- Much less jarring against dark theme
- Better integration with overall design language
