refactor: [30388f42] Entferne Legacy-Token-Dateien und Abhängigkeiten

- Bereinigt alle Dockerfiles (market, content, b2b) von COPY gemini_api_key.txt.
- Aktualisiert market_intel_orchestrator.py und b2b_marketing_orchestrator.py, um API-Keys strikt aus Umgebungsvariablen zu lesen.
- Verhindert Build-Fehler durch fehlende lokale Token-Dateien.
