Ändere Standard-Default für max.text.characters von 5000 auf 1000

Der bisherige Standard-Default von 5000 Zeichen löste gemäß Spezifikation
sofort eine starke Warnung in der GUI aus (Schwellenwert: >3000).
Dies ist nicht benutzerfreundlich.

Der neue Standard-Default ist 1000 Zeichen (unkritisch laut Spec).
Das entspricht einer besseren Balance zwischen KI-Input-Größe und
Benutzerwarnung beim Start.

Änderungen:
- GuiConfigurationTemplateFactory: Standardvorlage auf 1000 geändert
- Alle *.properties-Beispieldateien aktualisiert
- Dokumentation in gui-bedienanleitung.md ergänzt
- Betroffene Tests angepasst (etwa 10 Testdateien)
- Alle 206 Tests bestehen nach der Änderung
