* Reuse IMAGE_REGISTRY_REGEX for docker_image validation

Replace the monolithic regex in docker_image validator with a
function-based approach that reuses get_registry_from_image() from
docker.utils for robust registry detection. This properly handles
domains, IPv4/IPv6 addresses, ports, and localhost while still
rejecting tags (managed separately by the add-on system).

* Address review feedback: reorder checks for efficiency

Check falsy value before isinstance, and empty path before tag check,
as suggested in PR review.
