feat(search): improve search UI with sticky bar and keyboard handling

- Add fixed search bar with glassmorphism effect (backdrop blur, semi-transparent)
- Implement clear search button in DaisyUI style
- Auto-hide keyboard on Enter key press and scroll events
- Remove search page title for cleaner UI
- Use DaisyUI theme-aware background colors instead of fixed white
- Add fixed padding offset for content below search bar
