🎨 feat(ui): enhance pricing components with improved icons and responsive design

- Replace copy button icon from semi-ui IconCopy to lucide-react Copy in PricingCardView
- Add conditional tooltip functionality to SelectableButtonGroup that only shows when text overflows
- Implement responsive table column behavior in PricingTableColumns with mobile-aware fixed positioning
- Use DOM-based overflow detection (scrollWidth vs clientWidth) for better performance
- Apply useIsMobile hook to conditionally set fixed: 'right' only on desktop devices

These changes improve user experience across different screen sizes and provide more consistent iconography throughout the pricing interface.
