Make updater dialog non-modal

Force the updater dialog to be non-modal so users can continue using
the application while checking for or downloading updates. This improves
user experience by not blocking interaction with the main window.

The dialog is explicitly set to non-modal in the constructor, overriding
any setting from the UI file.
