test(ios): Path A - keep useFrameworks:static + forceStaticLinking ExpoUI/GlassEffectView

Pivot: removing useFrameworks fixed SwiftUICore but broke legacy pods (udp <React/...>), and use_modular_headers! didn't help (prebuilt React VFS). Instead keep useFrameworks:static (udp & all legacy pods keep working) and force-static-link the SwiftUI pods (ExpoUI=@expo/ui, GlassEffectView) so they stop propagating the SwiftUICore framework auto-link to the app target. forceStaticLinking is the documented expo-build-properties fix for Swift pods that break under static frameworks.
