Unicode Normalisierung:
clean_text nutzt nun unicodedata.normalize("NFKC", ...) zur Vereinheitlichung ambigue Unicode-Zeichen.
Umsatz-Extraktion:
In extract_numeric_value wird nun vor der Regex-Suche nichtbrechende Leerzeichen (\xa0) durch normale Leerzeichen ersetzt.
Bei fehlender Umwandlung (z. B. wenn kein numerischer String gefunden wird) wird ein Debug-Log ausgegeben, der den Original-Rohtext zeigt.
Mitarbeiterextraktion:
Gleiche Methode wie bei Umsatz, wobei die Mitarbeiterzahl als ganze Zahl zurückgegeben wird.
Flexible Regex (unter Nutzung von in im Vergleich) fängt Varianten ab, sodass z. B. "4.175 (2021/22)" zu "4175" wird.
