feat: real service runtime — private networks, replicas, lifecycle, rollback

Services now reconcile into actual Docker containers instead of
bookkeeping rows:

- Per-project bridge network with service-name DNS aliases and
  ${{service.KEY}} env expansion (HOST/PORT builtins)
- Replicas, published ports, Traefik domain routing, health checks,
  restart policies persisted on the service spec; spec-hash drift
  recreates containers on redeploy
- Lifecycle API: start/stop/restart/redeploy, live runtime state,
  real image rollback (replaces the fake sleep)
- Manual scale and PUT replicas reconcile live containers; service
  and project delete remove their containers and the project network
- Canvas: real URLs, replica badges, env filter, right-click
  deploy/restart/stop/delete menu, empty state
- Service detail: real lifecycle buttons, live replica/URL strip,
  Networking editor, ${{ }} variable helper
- Fix prebuilt-image pulls racing the tag (drain the pull stream)

 ## Features
 
-- **Project canvas** — visual service topology, groups, drag/drop, auto-inferred connections
+- **Project canvas** — visual service topology, groups, drag/drop, auto-inferred connections, right-click lifecycle actions
-- **Deployments & builds** — Docker deploys with history, logs, rollback, live build status
+- **Private networking** — every project gets an isolated Docker network; services reach each other by name (`web:3000`) and share variables via `${{service.KEY}}` references
+- **Deployments & builds** — Docker deploys with history, logs, image rollback, live build status
+- **Runtime** — replicas, published ports, domains, health checks, restart policies; start/stop/restart/redeploy from canvas or service page
 - **Git integration** — GitHub, GitLab, Bitbucket, Gitea; webhooks, GitHub App
 - **Managed databases** — one-click provisioning with backup/restore
 - **Metrics** — per-service Docker stats plus host CPU/memory/disk telemetry
