feat(i18n): implement astro i18n integration and refactor locale handling

- Add i18n configuration to astro.config.mjs with default locale and routing
- Refactor language handling to use Astro.currentLocale instead of URL parsing
- Update tsconfig to include only necessary files for better type checking
- Improve LanguageSwitcher to handle routing based on astro i18n config
- Add new translation keys and update components to use dynamic titles
- Simplify MotionWrapper component by removing unused default animations
