feat(analytics): update Google Analytics integration and improve fetch interception

- Refactored Google Analytics proxy routes in the Next.js configuration to enhance fallback handling.
- Improved fetch interception logic in the RootLayout component for more robust handling of Google Analytics requests, including support for `sendBeacon`.
- Updated the analytics script source to align with new API routes for better tracking accuracy.
