🎨 refactor(ModelPricing): enhance UI/UX with modern design ModelPricing component

This commit implements a comprehensive UI/UX overhaul of the ModelPricing component,
focusing on improved aesthetics and responsiveness while maintaining existing API logic.

Key improvements:
- Redesigned status card with gradient background and floating elements
- Implemented responsive grid layout for pricing metrics
- Enhanced visual hierarchy with Semi UI components
- Added smooth transitions and hover effects
- Optimized spacing and typography for better readability
- Unified design language with PersonalSettings component
- Integrated Tailwind CSS 3.0 utility classes
- Added decorative elements for visual interest
- Improved mobile responsiveness across all breakpoints
- Enhanced accessibility with proper contrast ratios

The redesign follows modern UI/UX best practices while maintaining consistency
with the application's design system.
