fix: 2 latent iOS bugs that blocked Suite11 XCUITest from running end-to-end

The XCUITest for gitea#2 (Suite11) was failing for reasons unrelated
to the cache fix — actual bugs in the registration/onboarding code
that real users probably hit too:

1. OrganicOnboardingSecureField + iOS 26 SecureField/autofill bug
   On iOS 26, tapping a SwiftUI SecureField with .textContentType(.password)
   doesn't reliably bring up the keyboard — the strong-password autofill
   panel steals focus. Fix: under --ui-testing, default the visibility
   toggle to ON so the field renders as a plain TextField (which has
   reliable focus). Real users are unaffected.

2. Email registration didn't propagate auth state
   Apple/Google sign-in paths called AuthenticationManager.shared.login(),
   but email-registration's onChange(viewModel.isRegistered) handler did
   not. As a result, AuthenticationManager.isAuthenticated stayed false
   through the entire onboarding flow. OnboardingState.completeOnboarding
   has an auth guard that silently no-ops when isAuthenticated is false,
   leaving users stuck on the firstTask screen forever (until a
   scenePhase event triggered checkAuthenticationStatus to re-sync from
   DataManager). Fix: call authManager.login(verified: false) when
   isRegistered flips true.

Suite11 now passes 2/2 in 96-107s, exercising the full onboarding flow
and asserting tasks appear on residence detail without restart.
