fix(ios): resolve scrollEnabled prop initialization timing issue

Store scrollEnabled state in an ivar and apply it when the scroll view becomes available, rather than attempting to set it before initialization. This ensures the prop works reliably regardless of when props are updated relative to UIPageViewController setup.

Also reset scrollEnabled to its default value (YES) in prepareForRecycle to prevent recycled components from retaining the previous instance's scroll state.
