The role-grants page is the authoring surface for LdapGroupRoleMapping
rows, but it had no @rendermode — so it rendered as static SSR and its
@onclick handlers (Add grant, Revoke) never fired. App.razor's <Routes/>
sets no global render mode; only ClusterDetail opted in.
- Add @rendermode RenderMode.InteractiveServer.
- Fix the SignalR hub URL: the page connected to /hubs/fleet-status,
but FleetStatusHub is mapped at /hubs/fleet. Static SSR masked this
(OnAfterRenderAsync never ran); enabling interactivity surfaced the
404 that terminated the circuit.
Verified in-browser: Add grant opens the form, a cluster-scoped grant
saves and lists, Revoke removes it.
