fix(settings): show machine-local sections for the representative environment

The Devices section on Integrations and the discovery sections on Source
Control interrupted an aggregate selection with an explanatory row or an
empty state. They now show the representative environment, named in the
section title, so the page is always usable and the environment crumb
narrows it when needed. The writing style and template rows mark mixed on
their own field only.
