refactor: migrated to next 16, updated fumadocs

- Deleted the empty middleware file as it was temporarily disabled for client-side i18n implementation.
- Updated `next`, `next-intl`, and `fumadocs` packages to their latest versions.
- Cleaned up the `next.config.ts` by removing the eslint configuration.
- Enhanced `tsconfig.json` with additional paths for `fumadocs-mdx`.
- Adjusted imports in `layout.tsx` and `request.ts` for better structure and functionality.
