Warenwirtschaft: AP-00 bis AP-08 + aktualisierter Entwicklungsplan

Umsetzung der Warenwirtschafts-/Produktmanagement-Erweiterung gemaess
Entwicklungsplan V4.0:

- AP-00: Regressionsbasis fuer 5.1-Features (ProductPhase51Test)
- AP-01: URL-Bugfixes B1/B2 (suppliers/packaging-items, breitere url-Spalten)
- AP-04/04.1: iPad-taugliche, vereinheitlichte Tabellen-Aktionen
- AP-05: Einstellungen "Allgemein" mit UST-Saetzen (tax_rates) und
  Lieferzeit-Vorlagen (delivery_times, inkl. Tage-Feld)
- AP-06: Lieferanten um Bestellweg, Bestell-Mail/-URL und Lieferzeit erweitert
- AP-07/07.1: INCI um Lieferanten-Mehrfachwahl, UST und Lieferzeit erweitert;
  Lieferanten-Detailansicht im Modal mit pflegbaren INCI-/Verpackungslisten
- AP-08: Einkauf um UST-Snapshot, Netto/Brutto-Automatik und Duplizieren erweitert

Entwicklungsplan aktualisiert: alle Klaerungspunkte (§5) vom Kunden beantwortet
und in die jeweiligen APs eingearbeitet (AP-02/03/09/13/15), neues AP-18
(Hinweise-Doku unter Einstellungen) ergaenzt. Naechster Schritt eindeutig
markiert: AP-09 (Produktion auf Hersteller-Rezeptur, kein Fallback, Warnung).
