## Summary
<!-- Provide a brief summary of the changes you have made and most
importantly what they aim to achieve -->
On iOS 15, when a WebViewController is hosted in a
UINavigationController with the navigation bar hidden, adding a
full-screen child UIViewController whose subtree contains a
UIHostingController triggers a UIKit safe-area inflation bug:
view.safeAreaInsets.top becomes roughly twice the real status-bar
height, the native statusBarView (pinned to
view.safeAreaLayoutGuide.topAnchor) oversizes, and WKWebView caches a
hit-test region from the inflated value — so taps near the top of the
page (e.g. the dashboard hamburger menu) land at the wrong content
coordinates until the device is rotated. iOS 16+ is unaffected.

Two callsites on main triggered this independently:

1. KioskSecretExitGestureViewController was installed unconditionally
from KioskModeManager.setup(using:) — even when kiosk mode wasn't
active. Now installed in enableKioskMode() and torn down in
disableKioskMode(); setup() only re-anchors it for an already-active
kiosk session.

2. WebViewController+EmptyState.setupEmptyState() called
addChild(emptyState.hostingViewController) unconditionally (added in
#4572 for iOS-16 SwiftUI safe-area propagation). The addChild +
didMove(toParent:) calls are now guarded with #available(iOS 16.0, *).
The empty state still renders on iOS 15; it just skips the parenting
that iOS 15 doesn't honor the same way anyway.

Updated the related test to XCTSkip on iOS 15 with a comment pointing at
this commit.

Fixes #4499.
