registry, verdaccio, portainer: full nox modules (ADR 0044/0046)

registry (docker v2): catalog/tags/delete tools, emits image.pushed (a build's
image is now pullable). verdaccio (npm): list/info tools, emits
package.published. portainer: endpoints/stacks/containers tools — tools-only,
since its only events are the underlying containers' lifecycle, which the host
owns. Typecheck; manifests parse.
