fix(image-updater): use argocd write-back for multi-source apps

Git write-back fails for Helm repo sources (multi-source): updater attempts to target external chart repos. Switch to argocd for plex, radarr, sonarr, flaresolverr, transmission, ollama. Keep git for prowlarr (chart path in this repo).\n\nCommitted via Codex CLI.
