feat(webui): an organization's workflows read only, a list, a step graph with the selected step's detail, and a Workflows card on the organization page (#1873)
#1973
The graph reads the existing GET /api/orgs/<id>/workflows; no new route and no write.
A stopped bus shows the data-ws-unread note, never "no workflows". An organization
with none says so and links Apply a pack only where this Console may apply one.
At 700px and below the graph runs top to bottom inside its own frame.
