Neues diora_tui/statusbar.py: StatusBar-Widget, unten rechts auf Bibliotheks- und Reader-Screen, zeigt Akkustand (psutil.sensors_battery(), degradiert sauber zu reiner Uhrzeit auf Geräten ohne Akku) + aktuelle Uhrzeit, sekündlich aktualisiert. Getestet: Anzeige und Aktualisierung auf beiden Screens verifiziert.
