Disable minimizing of SettingsWindow.

The settings window must be closed before translations can run, since some settings are only applied on close.
Additionally, there is no crash-safe infrastructure to prevent errors when interacting with settings during translation.
This is not ideal UX and should be reworked later, but keep it like this for now.
