Atlas org map — co-managing companies (PR #16037)

This is the admin org map, rendered from the real OrgMapView component over the bench fixture (benchAtlasData() + benchOrgGroups() + benchOrgManagers()), server-rendered and screenshotted headless. The fixture is synthetic, with no customer data. A card appears in prod only where a live co-manager arrangement exists.

Sandbox Co co-manages Alder Two today. It is drawn as a card inside Park West's own tree, with a solid line to the building, so no line leaves the tree. Its arrangement on Alder One has ended, so there is no line there.
Company org_far co-manages Alder Three but is not in the company list. It is drawn by id and badged not in the company list.
A row naming Park West itself is not a co-manager and draws nothing.
Known limit, carried from the groups review: middle-lane cards share one bus line. The table under the map and the text dump name the building each card runs.

Org map: Park West tree with line-sets, two groups and two co-managing company cards in the middle lane, three buildings on the right
