Rofi/Waybar aufräumen: tote Scripts entfernen, Themes konsolidieren

- GTK-Style-Script und Template-System entfernt (Catppuccin fest)
- 15 tote/inkompatible Scripts gelöscht (Hyprland, X11, Duplikate)
- Rasi-Themes von Einzelordnern in themes/ konsolidiert
- Waybar: Timezone fix, BAT0, JSON-Struktur, Icons restored
- Waybar: GTK-Menu durch wlogout on-click ersetzt
- Alle Script-Pfade auf /etc/xdg/rofi/themes/ aktualisiert
- moonarch-session als Rofi-basierte Übergangslösung hinzugefügt
- moonarch-dnd: broken pipe bei Waybar-Restart behoben
- Style.css vom System übernommen
