Web: Chargenliste (mit Sammel-Lagerort) + Ladezustand auf allen Tabellen

Neue Seite "Chargen": alle Chargen ueber alle Artikel (Artikel, Menge, MHD,
Lagerort, eingelagert). Lagerort je Zeile direkt aenderbar; alle Chargen ohne
Ort per Klick zuweisbar (bulk-location) - gut, wenn der Lagerort erst spaeter
angelegt wurde.

DataTable bekommt einen loading-Prop: waehrend des Ladens steht "Wird geladen..."
statt der Leer-Meldung. Auf ALLEN Tabellen angewendet (Produkte, Mindestbestaende,
Kategorien, Gruppen, Einheiten, Gebinde, Einzelstuecke, Chargen).
