Feature: Massenbearbeitung für Lagerorte, QR-Codes für Kisten, Tisch-Leeren Button und Fixes

     *   Neuer Menüpunkt zur Verwaltung (Bearbeiten, Löschen, Hinzufügen) von Kategorien analog zu den Herstellern implementiert.
     *   Kategorien können nun mit individuellen Farben (Hex-Code per Color-Picker) versehen werden. Diese Farben werden in der Detailansicht von Packlisten sowie in der Kachelansicht von Artikeln als farbige Badges dargestellt.
     *   Das Tortendiagramm auf dem Dashboard (`index.php`) nutzt nun ebenfalls die individuellen Kategorie-Farben.
-    *   Dashboard (`index.php`) um zusätzliche Haushalts-Statistiken erweitert (Gesamtzahl Artikel, Packlisten, Vorlagen, Rucksäcke).
+    *   Dashboard (`index.php`) um zusätzliche Haushalts-Statistiken erweitert (Gesamtzahl Artikel, Packlisten, Vorlagen, Rucksäcke). Packlistenvorlagen werden aus dem Gewicht-Diagramm ausgeschlossen.
     *   Kachelhöhe in der Artikel-Übersicht und im Packlisten-Editor (`manage_packing_list_items.php`) leicht angepasst. Hover-Bilder in Kacheln entfernt und leere Felder symmetrisch ausgerichtet.
     *   Anzeigename wird nun auch auf dem Dashboard (`index.php`) und in der Kategorienverwaltung korrekt angezeigt.
+    *   Massenbearbeitung (Bulk Actions): In der Artikel-Listenansicht können nun mehrere Artikel über Checkboxen ausgewählt und gleichzeitig in einen neuen Lagerort verschoben werden. Die Auswahl bleibt auch bei Filteränderungen bestehen.
+    *   Barcode für Lagerorte: In der Lagerort-Verwaltung kann für jeden Lagerort ein QR-Code generiert und angezeigt werden. Dieser führt zu einer für Smartphones optimierten, öffentlichen Ansicht des Kisteninhalts (ohne Login nutzbar).
+    *   Packlisten-Editor (`manage_packing_list_items.php`): Ein neuer Button "Tisch leeren" ermöglicht es, alle aktuell auf dem virtuellen Tisch liegenden Artikel mit einem Klick in die Lagerorte zurückzuräumen.
