Replaces the 188KB ConfigMap-embedded HTML with a proper Blazor Server
deployment (fc-intranet-web:latest on port 5300). The old nginx deployment,
ConfigMaps (intranet-html, intranet-nginx-conf), and all embedded HTML are
removed. The intranet is now a .NET 10 Blazor app with live health monitoring,
REST API, 49 pages, and the unified Blue Jay theme.
