feat: add service status monitoring to dashboard with parallel health checks for 14 services

Add SERVICE_DEFINITIONS list with Radarr, Sonarr, SABnzbd, Jellyfin, Seerr, Prowlarr, Easynews as Indexer, qBittorrent, Bazarr, Lingarr, LibreTranslate, Sonarr-Prowlarr Proxy, Radarr-Prowlarr Proxy, and Dashboard. Add check_service() to perform HTTP/API health checks with configurable timeout. Add refresh_services() to run checks in parallel using service_check_executor ThreadPoolExecutor with 16 workers.

+## Dienststatus
+
+Der Dashboard-Tab prüft zusätzlich Jellyfin, Seerr, Prowlarr, Easynews as Indexer,
+qBittorrent, Bazarr, Lingarr, LibreTranslate sowie die Sonarr-/Radarr-Prowlarr-Proxies.
+Die Prüfungen laufen parallel im Hintergrund und blockieren die Seite nicht.
+
+Die Standardnamen funktionieren, wenn die Container im selben Docker-Netzwerk liegen.
+Für qBittorrent muss `QBITTORRENT_URL` auf eine aus dem Dashboard-Container erreichbare
+URL zeigen, zum Beispiel `http://host.docker.internal:8080` oder die Host-IP.
+
+```env
+JELLYFIN_URL=http://jellyfin:8096
+SEERR_URL=http://seerr:5055
+PROWLARR_URL=http://prowlarr:9696
+EASYNEWS_INDEXER_URL=http://easynews-as-indexer:8081
+QBITTORRENT_URL=http://HOST_ODER_IP:8080
+BAZARR_URL=http://bazarr:6767
+LINGARR_URL=http://lingarr:9876
+LIBRETRANSLATE_URL=http://libretranslate:5000
+SONARR_PROWLARR_PROXY_URL=http://sonarr-prowlarr-proxy:8080
+RADARR_PROWLARR_PROXY_URL=http://radarr-prowlarr-proxy:8080
+SERVICE_CHECK_TIMEOUT=3
+SERVICE_REFRESH_SECONDS=30
+```
+
+Für die bereits vorhandenen Container sind keine zusätzlichen Compose-Services nötig;
+sie müssen im gemeinsamen `media-stack_default`-Netzwerk erreichbar sein. Falls
+qBittorrent nicht über `host.docker.internal` erreichbar ist, kann unter Linux je nach
+Docker-Konfiguration dieser Eintrag ergänzt werden:
+
+```yaml
+extra_hosts:
+  - "host.docker.internal:host-gateway"
