Refactor static page styles and update version text

- Changed the class name from 'euText' to 'versionText' in the Footer component for better clarity and semantic meaning.
- Updated CSS styles for 'euText' to improve layout and presentation, including changes to display properties and text alignment.
- Introduced new styles for 'versionText' to enhance visual separation and readability of the version information.
