Add additional Docker apps and Kopia container backup

New Docker applications:
- Jellyfin (free media server with hardware acceleration)
- Frigate NVR (AI-powered object detection)
- Caddy (reverse proxy with automatic HTTPS)
- ddclient (dynamic DNS updater)
- ntfy (self-hosted push notifications)
- Uptime Kuma (service uptime monitoring)
- wg-easy (WireGuard VPN with web UI)
- Traccar (GPS tracking server)
- Portainer (Docker management UI)

Container backup system:
- Kopia backup for all Docker container data
- Backup script for configs, databases, app state
- Restore script for disaster recovery
- Backs up Immich memories, Emby metadata, Minecraft worlds, etc.

All apps use docker-compose in ~/docker/{appname}/ with storage on
primary drive where appropriate.
