Add Prowlarr, Portainer, and Bazarr as default services

[joshdev8]

Summary

• Adds three services to docker-compose.yml that were previously listed as "not included but recommended":
  • Prowlarr (port 9696, media_network) — single indexer manager that feeds Radarr/Sonarr, replacing per-*arr indexer config.
  • Portainer (port 9000, monitoring_network) — Docker management UI. Mounts /var/run/docker.sock for full host control.
  • Bazarr (port 6767, media_network) — subtitle management against the same ${USERDIR}/plex/media library Radarr/Sonarr already write to.
• README and CLAUDE.md updated: service tables, network architecture lists, Mermaid diagram (now shows Prowlarr → *arrs and Bazarr → Plex), and a callout flagging that Portainer's socket mount grants root-equivalent host access.

Type of change

• New service or feature (feat/)
• Documentation (docs/)

Validation

• docker compose config parses cleanly with placeholder env values
• All three services are on the correct network(s) and listed in the README service table
• No new env vars required — services use the existing PUID/PGID/TZ/USERDIR contract
• Tested locally on a host with real .env (deferred — config edits only)

📝 Walkthrough

Walkthrough

Adds three services to the Plex stack—Portainer for Docker container management, Prowlarr for media indexing, and Bazarr for subtitle management—configured in Docker Compose on appropriate networks, documented with architecture diagrams and tables, and accompanied by technical network topology and security warnings.

Changes

Plex Stack Service Expansion

Layer / File(s)	Summary
Service Definitions in Docker Compose docker-compose.yml	Portainer service connects to monitoring_network on port 9000, mounts Docker socket, and persists data via portainer_data volume. Prowlarr and Bazarr join media_network on ports 9696 and 6767, with config directories and Bazarr's /media mount to Plex storage. Named volumes extended for all three services.
User-Facing Documentation in README README.md	Architecture diagram updated to show Prowlarr indexer connections feeding Radarr/Sonarr and Bazarr subtitle fetching for Plex. Content Management table adds Prowlarr and Bazarr entries. Monitoring table adds Portainer row. Portainer note section expanded with security warning about Docker socket read-write access and root-equivalent host privileges, plus guidance on securing admin credentials.
Technical Architecture & Security Documentation CLAUDE.md	Network membership redefined: monitoring_network now includes Portainer, media_network includes Prowlarr and Bazarr. Reachability explanation specifies that Radarr/Sonarr are accessible from Seerr, Prowlarr, and Bazarr via both relevant networks. New explicit warning documents that Portainer mounting Docker socket read-write constitutes host-equivalent access.

Poem

🐰 Three new helpers join the fray,
Portainer guards the Docker way,
While Prowlarr seeks and Bazarr finds,
Subtitles for all media kinds—
The Plex stack grows with careful care! 📺✨
