Backup: services/backup.py (Memory-SQLite inkl. WAL/SHM + Configs, retain 7) + deploy/backup.sh + POST /api/system/backup + GET /api/system/backups. Services-Health: GET /api/system/services (aggregierte Reachability + Observability-Links). Frontend: SystemView mit Dienste-Health + Backup- Button + Links; Theme-Toggle (Hell/Dunkel, persistent). Lokal verifiziert: Backup-Snapshot + services-Aggregat (TestClient), Frontend-Build + Browser (Light-Mode bestaetigt via computed styles). Damit Phasen 0-5 lokal fertig. Docs aktualisiert.
