Currently, there is a request to create a container

```gql
mutation createContainer {
  createContainer(
    image: "node:22-alpine"
    cmd: ["tail", "-f", "/dev/null"]
    labels: { test: "SDfsdf" }
  ) {
    ...DockerContainer_
  }
}

```



We get an error

```text
{
  "errors": [
    {
      "message": "(HTTP code 404) no such container - No such image: node:22-alpine ",
      "locations": [
        {
          "line": 16,
          "column": 3
        }
      ],
      "path": [
        "createContainer"
      ],
```

This is because the image has not been downloaded yet. We need to:
1\. Add a separate resolver for downloading images
2\. Add a check to the container creation resolver to see if the image already exists, and if not, download it, and only then create the container.

Add docker image download feature

## Context
The pilot of an arbitrary project confirmed the Narasim → external DinD → internal Docker Compose → application scheme. Currently, `buildAndRunProject` does not automatically connect the external container to the Traefik network. When both `bridge` and `docker_default` were present simultaneously, Traefik selected the wrong IP; a working launch required manually connecting `docker_default`, disconnecting `bridge`, and restarting the container.

## What to work on
- Make the Traefik network part of the standard project startup.
- Eliminate ambiguous IP selection when multiple Docker networks are present.
- Define the minimum routing contract: domain/host, internal HTTP port, unique router/service names, entrypoint/TLS.
- Do not require publishing a separate host port for each project.
- Test running multiple child projects simultaneously.
- Verify that the solution works identically locally and on the target server.

## Acceptance Criteria
A new Docker Compose project is launched via the API, automatically becomes accessible via Traefik at the assigned host/domain, and requires no manual `docker network connect/disconnect` or individual host ports.

Automate the connection of launched projects to the shared Traefik network without manual Docker operations.
