docs: Update Docker installation guide for working deployment

- Fix image reference: riffcc/dragonfly:v0.1.0-alpha1 → ghcr.io/riffcc/dragonfly:latest
- Add restart policy, RUST_LOG env var, proper volume name
- Add PXE boot networking section (host mode for DHCP/TFTP)
- Add custom port and data persistence/backup sections
- Update quick-start Docker and native download URLs to use latest release
- Use docker compose (v2) instead of docker-compose

+
+### Networking for PXE boot
+
+The default port-forwarded configuration works for the web UI and basic management. If you need PXE boot functionality (DHCP and TFTP), you'll need host networking:
+
+```yaml
+services:
+  dragonfly:
+    image: ghcr.io/riffcc/dragonfly:latest
+    restart: unless-stopped
+    network_mode: host
+    volumes:
+      - dragonfly-data:/var/lib/dragonfly
+    environment:
+      - RUST_LOG=info
+
+volumes:
+  dragonfly-data:
 ```
-docker-compose up -d
+
+Host networking is required because DHCP uses broadcast packets and TFTP requires direct socket access, which don't work through Docker's port forwarding.
+
+### Customising the port
+
+To run on a different port, change the port mapping:
+
+```yaml
+    ports:
+      - "8080:3000"  # Access on port 8080 instead
 ```
 
-Visit the web interface at http://localhost:3000
-(or `http://your-hostname:3000` if you're not running it locally)
+### Data persistence
+
+All Dragonfly data (database, templates, boot images) is stored in the `dragonfly-data` volume. This persists across container restarts and upgrades.
+
+To back up your data:
+
+```bash
+docker run --rm -v dragonfly-data:/data -v $(pwd):/backup debian:trixie-slim tar czf /backup/dragonfly-backup.tar.gz /data
+```
