Interaktionsoptionen und UI-Verbesserungen

Neue Methode `RefreshFocusedOptions()` hinzugefügt, um die Optionen des fokussierten Akteurs nach einer Interaktion zu aktualisieren. Änderungen an der Navigation im Kontextmenü: Begrenzte Navigation ersetzt zyklische Navigation.

`FInteractionOption` erweitert um `TextColorOverride` und `HighlightColorOverride`, um individuelle Farben für Optionen zu ermöglichen.

UI-Widgets (`InteractionOptionEntryWidget`) angepasst, um Hintergrund- und Hervorhebungsfarben dynamisch zu setzen. Hinweistext für sekundäre Interaktionen zeigt nun spezifische Optionennamen an.
