Subject: [PATCH] Fix LoadingScreen template: bind Foreground to ProgressRing
 and use AccentBrush by default

### Fix: LoadingScreen does not apply Foreground to ProgressRing

#### Problem
The `LoadingScreen` control exposes the `Foreground` property, but it is not used within the control template. As a result, setting `Foreground` has no effect on the visual appearance of the loading indicator.

Additionally, the style contains duplicate `Background` setters, where the first one is overridden.

#### Changes
- Bind `Foreground` to the inner `ProgressRing` via `TemplateBinding`
- Add a default `Foreground` value using `AccentBrush` to match Wpf.Ui theming
- Remove the redundant `Background` setter

#### Result
- `Foreground` now correctly controls the `ProgressRing` color
- Default appearance follows the current theme accent color
- Cleans up redundant style definition

#### Example
```xml
<ui:LoadingScreen Foreground="Red"/>

Now correctly changes the loading indicator color.
