.Net MAUI Localization

### Description

Localization is not working completely. I am using shell and when I change the language at runtime some texts are changed but not all of them. Some pages in the stack don't get translated. If I close the app and run it again the text in all pages is displayed in the correct language (I am saving the user setting to the device). The Shell menu localization works always, so I think this is a bug.

I also noticed that in Android the Shell flyout disappears when you click on the page content (which I expect is the desired behavior), in windows you have to click in the hamburger button for the flyout to hide. When changing the language programmatically, in windows the application loses the title bar in all the pages, in Android it works as expected.

Using FontAwesome for the icons in shell is nice but the alignment in Android is not very good and there is no padding or margin property to adjust their position.

In preview 13, I was able to publish to my IOs physical device in preview14 not anymore.

### Steps to Reproduce

I am using simple app with Shell and some pages to test navigation, localization and theming. I am including a video with the issues:

Code to change language at runtime:

```csharp
...
switch (App.Language)
{
case "English":
selCulture = "en-US";
break;
case "Spanish":
selCulture = "es-CO";
break;
default:
break;
}

CultureInfo.CurrentUICulture = new CultureInfo(selCulture, false);
Settings.Language = App.Language;

Application.Current.MainPage = new AppShell();
await Shell.Current.GoToAsync($"//{nameof(SettingsPage)}");
...
```

.

### Version with bug

Preview 14 (current)

### Last version that worked well

Unknown/Other

### Affected platforms

iOS, Android, Windows

### Affected platform versions

Android 12, Windows 11

### Did you find any workaround?

No, I have not tried any work arounds

### Relevant log output

_No response_

Start with the runtime language-change snippet, especially the replacement of MainPage with AppShell and navigation to SettingsPage, then review the attached video. The report combines localization, Shell flyout and title-bar behavior, icon alignment, and iOS publishing across Android, Windows, and iOS; done would require separating these symptoms and reproducing each one reliably.
