* Fixed: Made a small improvement to the sidebar entries for "About the app" and "Support app."

* Introduced the 'Support kiwix' option, which is configurable in the navigation for custom apps. If the custom app is set to display the "Support" menu item in navigation, it will be shown; otherwise, it will be hidden from the app.
* Replaced the "kiwix" and "the" prefixes in "Support kiwix" and "About the app" with the app name in the navigation.
