iOS 26.1: `IASKAppSettingsWebViewController` shows Autolayout and Sandbox warnings and also redirects to Safari with domain https://consentcdn.cookiebot.eu

With the latest InappSettingsKit 3.9.2 I see 2 new behaviours while testing on device with iOS 26.1 (23B82).
When I tab the row that should open `IASKAppSettingsWebViewController`:

### 1. Xcode 26.1 shows 2 warnings about Autolayout constraints in the Console log:
```
Unable to simultaneously satisfy constraints.
	Probably at least one of the constraints in the following list is one you don't want. 
	Try this: 
		(1) look at each constraint and try to figure out which you don't expect; 
		(2) find the code that added the unwanted constraint or constraints and fix it. 
	(Note: If you're seeing NSAutoresizingMaskLayoutConstraints that you don't understand, refer to the documentation for the UIView property translatesAutoresizingMaskIntoConstraints) 
(
    "<NSAutoresizingMaskLayoutConstraint:0x129dd7c50 h=--& v=--& _TtCC5UIKit19NavigationButtonBar15ItemWrapperView:0x129c05500.width == 0   (active)>",

    "<NSLayoutConstraint:0x116ab1720 H:[_UIButtonBarButton:0x129c5f480]-(0)-|   (active, names: '|':_TtCC5UIKit19NavigationButtonBar15ItemWrapperView:0x129c05500 )>",
    "<NSLayoutConstraint:0x1079c0320 'IB_Leading_Leading' H:|-(7)-[_UIModernBarButton:0x129f28700]   (active, names: '|':_UIButtonBarButton:0x129c5f480 )>",

)

Will attempt to recover by breaking constraint 
<NSLayoutConstraint:0x1079c2300 'IB_Trailing_Trailing' H:[_UIModernBarButton:0x129f28700]-(7)-|   (active, names: '|':_UIButtonBarButton:0x129c5f480 )>

Make a symbolic breakpoint at UIViewAlertForUnsatisfiableConstraints to catch this in the debugger.
The methods in the UIConstraintBasedLayoutDebugging category on UIView listed in <UIKitCore/UIView.h> may also be helpful.
```

Also another stack trace is shown:

```

And another failure:
```
Failed to open URL  about:blank :  Error Domain=NSOSStatusErrorDomain Code=-10814 "(null)" UserInfo={_LSFile=LSDOpenService.mm, _LSLine=282, _LSFunction=-[_LSDOpenClient openURL:fileHandle:options:completionHandler:]}
```

### 2. The app is moved to the background and Safari opens
Safari loads URL https://consentcdn.cookiebot.eu/sdk/bc-v4.min.html which is an empty page.
**Why is this redirect performed?**

### Notes

- With the same Xcode 26.1 and an iPhone with iOS 18.7.2 the same behaviour is observed on device. However, in issue 1 **only the last failure** is shown in the Xcode console log:
```
Failed to open URL  about:blank :  Error Domain=NSOSStatusErrorDomain Code=-10814 "(null)" UserInfo={_LSFile=LSDOpenService.mm, _LSLine=282, _LSFunction=-[_LSDOpenClient openURL:fileHandle:options:completionHandler:]}
```
- With InappSettingsKit 3.8.5 and the same Xcode 26.1 and on both iPhones, these issues are not present, except that this log is observed too:
```
Failed to open URL  about:blank :  Error Domain=NSOSStatusErrorDomain Code=-10814 "(null)" UserInfo={_LSFile=LSDOpenService.mm, _LSLine=282, _LSFunction=-[_LSDOpenClient openURL:fileHandle:options:completionHandler:]}
```
- The used URL in the plist is https://www.atagverwarming.nl/over-atag/contact/ and is retrieved from the localisation file with key `contactAtagLocalizedUrl` like:

<img width="614" height="186" alt="Image" src="https://github.com/user-attachments/assets/69870eef-4cbd-4772-8bb2-0ac1f945314f" /> 
 
- This URL shows a cookie popup from Cookiebot, which is exactly the domain that is being opened in Safari with InappSettingsKit 3.9.2:
