🐛 Fixed Side Panel Hover Logic for Multi-Select

🔧 Bug Fix:
- Removed persistent panel visibility for selected cards
- Side panels now properly hide when hovering away
- Selection state no longer interferes with hover behavior
- Maintains smooth hover delay and animations

✨ Improved UX:
- Side panels only appear on hover, regardless of selection
- Clean hover interactions without sticky panels
- Consistent behavior across all cards
- Better multi-select workflow

The side panels now behave correctly - they only show on hover and hide when you move away, even for selected cards! 🎯
