Backend-Arbeitsstand: ERP-Sync, Lieferlebenszyklus, Reports + config.toml

Bringt das Backend vom initialen Skeleton auf den aktuellen Arbeitsstand
(Clean Architecture: domain → application → infrastructure → api).

Wesentliche Bereiche:
- ERP-Anbindung (MSSQL-Pull der Touren, Import-Scheduler, Rückschreiben)
- Lieferlebenszyklus: Scan/Hold/Cancel/Complete, Gutschriften, Notizen,
  Bild-Anhänge, Unterschriften, PDF-Lieferreport → DOCUframe
- Stammdaten: Kunden, Artikel, Lager, Zahlungsarten, Services
- Keycloak-JWT-Gate + Fahrer-Provisionierung via Admin-API
- Admin-API-Key-Gate (X-Admin-Api-Key) für Maschinen-Endpunkte

Jüngste Änderungen dieser Session:
- Belegspezifische Kontaktdaten: alle ERP-Adressen (Beleg-/Liefer-/
  Rechnungsadresse, Ansprechpartner, Kundenstamm) mit Telefon/Mobil/
  E-Mail werden gesynct (Migration 0029, MSSQL-Query, TourDetails)
- Konfiguration von .env (envy/dotenvy) auf config.toml (toml/serde)
  umgestellt; Vorlage config.example.toml, Pfad via HOLZLEITNER_CONFIG

Nicht im Repo (per .gitignore): config.toml (Secrets), data/ (Laufzeit-/
Kundendaten), demo.mp4, .claude/, variocontrol-ai/.
