feat(ui): SoC Refactoring & Config Validation

- Theme Context ausgelagert (ThemeContext.tsx + useDarkMode.ts)
- Config Validation mit TMDB-API-Key Pflicht (config_validation.py)
- Cache Key Centralization (cache/keys.py)
- CD-Ripping mit abcde implementiert (Worker)
- Docker Compose mit Healthchecks & LOG_LEVEL
- ROADMAP.md & SAVEPOINT.md aktualisiert

+## Etappe 9: SoC Refactoring & Config Validation
+
+**Ziel:** Code-Qualität durch saubere Trennung + Konfigurations-Validierung.
+
+**Was gebaut wird:**
+- Theme-Context aus App.tsx in eigenes Context auslagern
+- Config Validation mit TMDB-API-Key Pflicht
+- Cache Key Centralization (cache/keys.py)
+- Worker Refactoring für bessere Trennung
+- Docker Compose mit Healthchecks
+
+**Fertig wenn:**
+- Theme-Logik in eigenem Context (ThemeContext.tsx)
+- Wiederverwendbare Dark Mode Helper (useDarkMode.ts)
+- TMDB-API-Key ist Pflicht (Fehler bei Fallback-UI)
+- Cache-Keys zentral definiert
+- Docker Healthchecks für API
+
+**Status:** In Arbeit
+
 ## Etappe 9: Proxmox-Integration
 
 **Ziel:** Ein-Click-Deploy auf Proxmox LXC.
