Verbessert: Wikipedia-Suchlogik erneut optimiert (Version 1.0.2)

- Wieder eingeführt: Kombination aus vollständigem Firmennamen, ersten zwei Wörtern und Domain-Fragment zur Suche
- Erhöhte Trefferwahrscheinlichkeit durch Titel-, Inhalts-, Domain- und Ähnlichkeitsprüfung
- Info aus Infobox (Branche & Umsatz) wird bevorzugt; Kategorien nur als Fallback
- Version in Spalte Q geschrieben zur Nachverfolgbarkeit
