fix(ios): update ScreenProtectorKit dependency and address Swift concurrency build errors

[cnkygmr]

screen_protector 1.5.3 still depends on ScreenProtectorKit 1.5.1, so iOS apps do not receive the iOS 16+ crash fix that exists in the ScreenProtectorKit 1.5.2 tag.

When overriding the dependency to ScreenProtectorKit 1.5.2, Xcode also reports Swift concurrency build errors around \.isKeyWindow, \.windows, and non-Sendable captures. Please update the native dependency and make the 1.5.2 iOS source compatible with current Xcode/Swift concurrency checks.
