<message>Update the cloud-init scripts to improve GTK theme settings by enforcing dark mode through gsettings and preserving the icon theme for a cohesive user experience. Additionally, enhance the first-boot script to install a Chromium kiosk launcher icon on the desktop and in the application menu, along with a five-tap close functionality for Chromium. These changes streamline the user interface and ensure a consistent dark theme across applications and the taskbar.
