feat: live Docker data — containers, services, logs, metrics via dockerode

- Backend: rewrote containers/services/logs/metrics routes to use dockerode
- docker-compose: mount /var/run/docker.sock, run backend as root
- .drone.yml: sync docker-compose.yml from Gitea on deploy
- Frontend: Containers page shows real data with wired start/stop/restart
- Frontend: Services page shows Docker Compose stacks with health status
- Frontend: Metrics page adds disk (docker df) and containers cards + chart legend
- Frontend: Logs page replaces text input with container dropdown + auto-refresh
