Live DSM API capture revealed the actual SYNO.Docker.Image/get
contract: a single JSON-encoded parameter named `identity` that
accepts both `name:tag` and `sha256:<hash>` forms. The 0.4.0 code
passed `name` + `tag` + `id` and was rejected by DSM with error 114.
Response shape also corrected — the endpoint returns flat top-level
fields (image, tag, id, digest, size, virtual_size, author,
docker_version, cmd, entrypoint, env, ports, volumes), NOT the
Docker-engine inspect shape with details.Config.* + RootFS.Layers
that the previous implementation assumed. Layer rendering removed;
digest / author / docker_version / volumes are now displayed.
Pre-resolution against list_images is no longer needed — the user
input goes straight into `identity` JSON-encoded.
Closes#4.
