Make a workspace page a dashboard and drop its coordinator from the rail

The workspace rail now lists only the bots attached to the workspace, with the back link returning to the workspace page from a bot's conversation. /admin/workspaces/<id> becomes a read-only dashboard (picture, context, latest activity, bots, computers) that links into the editable settings page.
