Remove next-view-transitions and use native View Transition API

- Remove external next-view-transitions dependency
- Use Next.js 16 native navigation and Safari 18+ native View Transition API
- Add ViewTransitionProvider for minimal wrapping with Safari 18+ detection
- Updated all Link imports from external package to next/link
- Removed link-wrapper.tsx and view-transitions-wrapper.tsx

This resolves Safari compatibility issues while maintaining transitions on modern browsers.
