fix: Linux asks with its own dialogs where zenity and kdialog are missing
Fedora Silverblue and other image-based GNOME systems ship neither tool,
so every question answered no (deleting a section, emptying the Recycle
Bin, Uninstall, installing an update), alerts and notices only reached
stderr, and the page date, time and SMB sign-in could not be asked.
Where neither tool runs, the app now runs itself as a small dialog
drawn with the interface kit (snowbound --dialog), which answers on
stdout as zenity does.
