feat: Interne Deduplizierung implementieren und Skript refaktorieren
- Skript zu company_deduplicator.py umbenannt mit Erhalt der Git-Historie - Hauptlogik in externen und internen Modus refaktorisiert - Interaktive Modus-Auswahl für den Benutzer hinzugefügt - Interne Deduplizierung zum Finden von Duplikaten innerhalb der CRM-Liste implementiert - Logik zur Gruppierung von Duplikatspaaren zu eindeutigen Clustern hinzugefügt - Eindeutige Dup_XXXX IDs den Duplikatsgruppen zugewiesen - Neue Spalte Duplicate_ID zurück in das Google Sheet geschrieben
