[iOS] TabBarDisabledColor is not applied when the TabBar is in a disabled state

[NafeelaNazhir]

Description

When a Tab is disabled (IsEnabled = false), the TabBarDisabledColor property is expected to change the icon and text color of the disabled Tab.
This works correctly on Android , but on iOS the TabBarDisabledColor is not applied, and the TabBar continues to use the default system disabled color.

Expected Output	Actual Output
Screen.Recording.2025-12-04.at.10.52.16.AM.mov	Screen.Recording.2025-12-04.at.11.19.26.AM.mov

Steps to Reproduce

1. Run the attached sample IsEnabledTabBarIssue 3.zip
2. Set TabBarDisabledColor="Green" in the Shell.
3. Disable one of the tabs.
4. Run the sample on iOS.
5. Observe that the disabled Tab does not use the green color and instead shows the default iOS disabled color.
