Show Docker images as sub-services under docker service

Agent changes:
- Added get_docker_images() function to list all Docker images
- Use docker images to show stored images with repository:tag and size
- Display images as sub-services under docker service with size in parentheses
- Skip dangling images (<none>:<none>)
- Images shown with active status (always present when listed)

Example display:
● docker                      active     139M     1MB
  ├─ ● docker_gitea           active
  ├─ ○ docker_old-app         inactive
  ├─ ● image_nginx:latest     (142MB)
  ├─ ● image_postgres:15      (379MB)
  └─ ● image_gitea:latest     (256MB)
