fix(admin): add InteractiveServer render mode to all interactive Blazor pages; fix wrong hub URLs

Eight pages were using @onclick handlers, Timers, or HubConnections but had no @rendermode,
causing interactivity to be silently dead under static SSR. Added @rendermode RenderMode.InteractiveServer
(with the required @using Microsoft.AspNetCore.Components.Web) to: AlarmsHistorian, Certificates,
Fleet, Home, Hosts, Reservations, DraftEditor, and ImportEquipment.

Also fixed two hub URL bugs: AclsTab and RedundancyTab were connecting to the non-existent
/hubs/fleet-status path; corrected to /hubs/fleet which matches the MapHub<FleetStatusHub>
call in Program.cs. Build: 0 errors, 0 warnings.
