Refactor i18n initialization and make UI adjustments

Converted the `initializeI18nClient` function to an asynchronous function for a more straightforward implementation. Simultaneously, made some tweaks to the UI components, such as altering dimensions in `site-footer.tsx` and `site-page-header.tsx`, and refactoring the `FooterSectionHeading` component for easier maintenance and improved readability.
