refactor: remove "Services" pages and migrate content to focused alternatives

- Removed `/services` and `/zh/services` pages. Migrated content to updated pages: `/uses`, `/about#contact-card`, and `/hire`.
- Removed Framer Motion for better performance and simpler animations in `LanguageSwitcher`, `GlassHeader`, and other components.
- Updated font sources to WOFF2 for better compression and added preload links for critical fonts.
- Optimized Vite configuration with manual chunking for React libraries.
- Replaced `client:load` with `client:idle` for non-critical client-side components like `GlassHeader`, `Footer`, and `BackToTop`.
