fix(wikipedia): Robustere Extraktion durch angepasste Infobox-Auswertung mit Synonym-Feldern

- XPath entfernt, da BeautifulSoup in Kombination mit Infobox-Selektor zuverlässiger
- Nur Branchen aus Infobox erlaubt, Kategorien nur als Fallback entfernt
- Verbesserte Ausgabe: Nur bei gefundenem Wikipedia-Link werden Werte eingetragen
- Versionskennung 1.0.6 eingeführt (Spalte Q)
