Pull request overview
Restores the BarViz startup loading indicator for the Interactive WebAssembly host (regressed during the hosting model migration in #6559) by reintroducing the initial loading UI and removing it once the client app has rendered.
Changes:
- Add a startup loading UI container to the BarViz host page, plus a small JS helper to remove it.
- Remove the loading UI from Blazor after the first client render via
OnAfterRenderAsyncJS interop.
