Added feature for part IPN suggest with category prefixes (#1054)

* Erweiterungstätigkeiten zur IPN-Vorschlagsliste anhand von Präfixen aus den Kategorien

* Umstellung Migrationen bzgl. Multi-Plattform-Support.
Zunächst MySQL, SQLite Statements integrieren.

* Postgre Statements integrieren

* SQL-Formatierung in Migration verbessern

* Erweitere IPN-Suggest um Bauteilbeschreibung.

Die Implementierung berücksichtigt nun zusätzlich die Bauteilbeschreibung zu maximal 150 Zeichen Länge für die Generierung von IPN-Vorschlägen und Inkrementen.

* Anpassungen aus Analyse vornehmen

* IPN-Validierung für Parts überarbeiten

* IPN-Vorschlagslogik um Konfiguration erweitert

* Anpassungen aus phpstan Analyse

* IPN-Vorschlagslogik erweitert und Bauteil-IPN vereindeutigt

Die IPN-Logik wurde um eine Konfiguration zur automatischen Suffix-Anfügung und die Berücksichtigung von doppelten Beschreibungen bei Bedarf ergänzt. Zudem wurde das Datenmodell angepasst, um eine eindeutige Speicherung der IPN zu gewährleisten.

* Regex-Konfigurationsmöglichkeit für IPN-Vorschläge einführen

Die Einstellungen für die IPN-Vorschlagslogik wurden um eine Regex-Validierung und eine Hilfetext-Konfiguration erweitert. Tests und Änderungen an den Formularoptionen wurden implementiert.

* Match range assert and form limits in suggestPartDigits

* Keep existing behavior with autoAppend suffix by default

* Show the regex hint in the browser validation notice.

* Improved translations

* Removed unnecessary service definition

* Removed german comments
