Fix Blazor activation render ordering and update dependencies (#4318)

## 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

## Dependency updates

|---------|------|----|
| TUnit | 1.17.54 | 1.24.18 |
| bunit | 2.6.2 | 2.7.2 |

| Microsoft.Testing.Extensions.CodeCoverage | 18.4.1 | 18.5.2 |
| Verify.TUnit | 31.13.2 | 31.14.0 |
| Microsoft.Xaml.Behaviors.Wpf | 1.1.135/1.1.141 | 1.1.142 |
| Microsoft.Maui.Controls (net10 only) | 10.0.41 | 10.0.51 |
| Xamarin.AndroidX.Preference | 1.2.1.16 | 1.2.1.17 |

TUnit implicit usings were enabled to match TUnit 1.24 requirements. One
test assertion was updated for TUnit 1.24 compatibility (nullable Func
evaluation change).

## Test plan

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