fix: 43 verwaiste Suffix-Vorlagen in Ketten zusammengeführt

- fix_orphan_chains.py: Findet Suffix-Dokumente (z.B. 0010/2025-1) ohne Kette
- Matcht automatisch mit Basis-Vorlage (0010/2025) → erstellt Kette
- 43 neue Ketten, 5 bestehende erweitert, 3 übersprungen (Basis fehlt)
- Status-Engine auf alle neuen Ketten angewendet
- Beispiel: Rüggeweg 0010/2025 + 0010/2025-1 → Kette 6313
