✨ feat(ui): add hover scale animation to header logo

Add smooth scale-up animation effect when hovering over the header logo to enhance user interaction experience.

Changes:
- Add `group` class to Link element to enable Tailwind group hover functionality
- Update transition from `transition-opacity` to `transition-all` for smooth scaling
- Increase hover scale from `scale-105` to `scale-110` (10% enlargement)
- Maintain 200ms transition duration for optimal user experience

The logo now smoothly scales to 110% size on hover and returns to original size when mouse leaves, providing better visual feedback for user interactions.
