Refactor the footer in App.vue to include the application version and improve layout with flexbox. Remove the version display from StatusBox.vue and update the app version in version.js from 3.0.0 to 3.1.0.
Add a new element in StatusBox.vue to show the application version. Update the refresh interval for status display from every 0.5 seconds to every 1 second for improved performance. Increment mobile app version to 0.8.0-alpha8 and version code to 9. Introduce new VersionScreen in the mobile app for displaying version information, and update navigation and mock data accordingly.
