* Pass registry credentials to add-on build for private base images
When building add-ons that use a base image from a private registry,
the build would fail because credentials configured via the Supervisor
API were not passed to the Docker-in-Docker build container.
This fix:
- Adds get_docker_config_json() to generate a Docker config.json with
registry credentials for the base image
- Creates a temporary config file and mounts it into the build container
at /root/.docker/config.json so BuildKit can authenticate when pulling
the base image
- Cleans up the temporary file after build completes

* Refactor registry credential extraction into shared helper
Extract duplicate logic for determining which registry matches an image
into a shared `get_registry_for_image()` method in `DockerConfig`. This
method is now used by both `DockerInterface._get_credentials()` and
`AddonBuild.get_docker_config_json()`.
Move `DOCKER_HUB` and `IMAGE_WITH_HOST` constants to `docker/const.py`
to avoid circular imports between manager.py and interface.py.
