Add comprehensive service stacks: Dockge, Homepage, Home Assistant, and all user services

- Add Dockge to infrastructure (primary over Portainer)
- Create dashboards.yml with Homepage and Homarr (AI-configurable)
- Create homeassistant.yml with HA, ESPHome, TasmoAdmin, Node-RED, Mosquitto, Zigbee2MQTT, MotionEye
- Create media-extended.yml with Readarr, Lidarr, Lazy Librarian, Mylar3, Calibre-Web, Jellyseerr, FlareSolverr, Tdarr, Unmanic
- Create productivity.yml with Nextcloud, Mealie, WordPress, Gitea, DokuWiki, BookStack, MediaWiki (all with databases)
- Create utilities.yml with Backrest, Duplicati, Uptime Kuma, Code Server, Form.io, Authelia Redis
- Add Homepage configuration templates (services.yaml, docker.yaml, settings.yaml, widgets.yaml)
  - All services include container names for Docker integration
  - Widgets configured for services that support them (Sonarr, Radarr, Plex, Jellyfin, etc.)
  - Organized by category with proper layouts
- Create docs/proxying-external-hosts.md - comprehensive guide for proxying Raspberry Pi and other external hosts via Traefik
- Update .env.example with all new service credentials and Homepage API keys
- Update infrastructure.yml to prioritize Dockge, add Dozzle, Glances, Docker Proxy
- All services configured with /opt/stacks paths, Traefik labels, and appropriate Authelia middleware
