Fix VoiceOver Accessibility Blocking UI Elements on iOS

Details:

Dex’s iOS app is currently not accessible via VoiceOver, Apple’s built-in screen reader. When VoiceOver is enabled, users cannot access or navigate UI elements on the screen.

Based on investigation and prior experience with iOS accessibility, this may be caused by a UI container (e.g. an overlay or styling layer) being marked with isAccessibilityElement = true, which prevents VoiceOver from reaching child elements within that view. This is a known issue pattern in iOS apps, especially when transparent overlays are used for layout or styling.
