feat(frontend): enhance UI components with animations and accessibility improvements

### Changes 🏗️
- Integrated `FadeIn` animations in `AgentsSection`, `FeaturedCreators`, `FeaturedSection`, `HeroSection`, and `BecomeACreator` components for improved visual appeal.
- Replaced static elements with `StaggeredList` in `FeaturedCreators` and `AgentsSection` for a more dynamic layout.
- Updated `SearchBar` to use `type="search"` and added `aria-label` for better accessibility.
- Enhanced `StoreCard` with focus-visible styles and keyboard navigation support.
- Refactored `FilterChips` to utilize `FilterChip` component for a more consistent design.

### Checklist 📋
- [x] Verified animations function correctly across components.
- [x] Ensured accessibility improvements are in place and tested.
- [x] Confirmed UI consistency with design specifications.
