Description

When applying FlowDirection="RightToLeft" in a .NET MAUI Shell, the layout is not fully mirrored as expected on iOS and Mac Catalyst.
Two related issues were identified in RTL mode:

Issue 1. Content Layout Issue:
When setting FlowDirection="RightToLeft" for shell, only Shell elements such as the flyout menu icon respect the direction. However, the Shell content (e.g., Label and page content) continues to render LeftToRight on iOS and Mac Catalyst.

Expected Output	Actual Output

Issue 2. Flyout Layout Issue:
When FlowDirection is set to RightToLeft, the flyout layout and item alignment do not properly updated when FlyoutBehavior="Locked".

Expected Output	iOS	Catalyst

Steps to Reproduce

1. Issue 1

• Set FlowDirection="RightToLeft".
• Observe both the Flyout and page content alignment.
• Refer to the above image for the expected output.

2. Issue 2

• Set FlowDirection="RightToLeft".
• Set FlyoutBehavior="Locked".
• Observe the Flyout menu icon, Flyout item alignment, and page content layout.
• Refer to the above image for the expected output.
