Fix Blazor activation render ordering and update dependencies

[glennawatson]

What changed for end users

Blazor components (ReactiveComponentBase, ReactiveInjectableComponentBase, ReactiveLayoutComponentBase, ReactiveOwningComponentBase) had a lifecycle ordering bug where property changes made during WhenActivated were not reflected in the UI. This happened because:

1. WhenActivated fires during OnInitialized -- your Rx chains execute and set reactive properties
2. Blazor renders the component
3. ViewModel change subscriptions are wired in OnAfterRender -- too late to catch changes from step 1

The fix adds a StateHasChanged() call after wiring subscriptions in OnAfterRender so the component re-renders with the latest state from activation. This results in one additional render cycle on first load but ensures the UI is always consistent.

Fixes #4317

Test plan

• All 12,514 tests pass across net8.0, net9.0, net10.0
• Full solution build succeeds with 0 warnings, 0 errors
• Blazor test render counts updated to reflect the additional activation render
