test: Add SwiftUI test to reproduce SwiftUI lifecycle only bugs

[noahsmartin]

Add a test to capture error in SwiftUI test app, reproduces the error fixed by #6264

#skip-changelog

Closes #6269

---

Note

Adds a UITest to assert capture(error:) returns a non-empty Sentry ID and updates the SwiftUI sample to surface that ID for testing.

• UITests (Samples/iOS-SwiftUI/iOS-SwiftUI-UITests/LaunchUITests.swift):
  • Import Sentry.
  • Add testCaptureErrorReturnsValidId that taps "Capture Error", reads errorId, builds SentryId, and asserts it’s not empty.
• SwiftUI app (Samples/iOS-SwiftUI/iOS-SwiftUI/ContentView.swift):
  • Add @State var errorId: SentryId? and display it with accessibilityIdentifier errorId.
  • Change captureErrorAction to a function that captures the error and stores the returned SentryId in state.
