    power: Fix blank-screen settings not applying
    
    The AdwComboRow widget has a selected-item property, while we were
    connecting to selected-index (which doesn't exist.
    
    It is likely that selected-index existed in the past in libhandy
    or libadwaita and this is a regression during the port to GTK4.
    
    Fixes #2025
