🔨 refactor(API): replace axios with fetch for getVersion and getHealth functions

🔨 refactor(MainPage): remove handleSaveFlow prop from MenuBar component
🔨 refactor(MainPage): export MenuBar component as named export
The axios library is replaced with the fetch API for the getVersion and getHealth functions to reduce the bundle size and improve performance. The handleSaveFlow prop is removed from the MenuBar component as it is not used. The MenuBar component is now exported as a named export to improve code readability and maintainability.
