⚡ Massive Performance Boost - Remove Heavy Hover Panels

🚀 Performance Optimizations:
- Completely removed complex side hover panels (massive DOM reduction)
- Eliminated 240+ lines of heavy panel HTML per card
- Removed expensive panel positioning calculations
- Simplified hover animations from 300ms to 200ms
- Removed redundant image scaling (double transform)

🎯 New Lightweight Hover System:
- Simple card scaling on hover (transform: scale(1.05))
- Slide-in action buttons in corners
- Checkbox & favorite in top-right corner
- Ownership indicator & add button in bottom-left
- All buttons use opacity transitions (GPU accelerated)

🔥 Fire-Themed Interactive Elements:
- Checkbox: Ember red accent color
- Favorite: Ember red background when active
- Add/Own button: Wood brown background
- Ownership indicator: Gold dot when owned
- All buttons have subtle hover scaling (scale(1.1))

📱 Enhanced Grid Layout:
- Removed right padding (no more panel space needed)
- Increased grid density: lg:4 cols, xl:5 cols, 2xl:6 cols
- Better space utilization across all screen sizes
- Cleaner, more focused card browsing experience

✨ User Experience Improvements:
- Much faster card grid rendering
- Smoother hover interactions
- Reduced layout shift and jank
- Cleaner visual hierarchy
- Quick access to essential actions

💾 Code Cleanup:
- Removed cardIndex and cardsPerRow props
- Eliminated panel positioning logic
- Simplified component structure
- Reduced bundle size significantly

The cards page should now be lightning fast! ⚡🔥
