The services sat in the curation column, beside the properties, while the
addresses that reach them were two columns away. They move under
Identity: what answers on a host belongs with how to reach it, and the
curation column now carries the properties alone.
Every section heading takes an icon — identity, services, monitoring,
activity, notes, properties, make & model — so a column is scannable
without reading each title. `Section` requires it, so a new section
cannot be added without one. The properties editor keeps its own plain
heading: it comes from the shared `PropertyList`, which the rack cable
panel also renders.
The three view columns carry a data-testid, which is what lets the
layout be asserted rather than eyeballed.
