Summary: The current ReactModalHostView implementation incorrectly applies system bar appearances by providing the wrong mask to the `setSystemBarsAppearance` method invocation. Per [this issue comment](https://github.com/facebook/react-native/issues/34350#issuecomment-1760339877), jaydonlau correctly identified that when the status bar is set to `light-content` (light icons, dark background), the function is called with both a `0` appearance and `0` mask, which should instead be provided with the `APPEARANCE_LIGHT_STATUS_BARS` mask. The first pass at this PR attempted to pull out the entire appearance from the activity, compare it against the dialog's appearance, and only use a mask of differing bits (see the `appearanceMask` variable). However, if the `android:windowLightStatusBar` attribute is ever set to true, this does not impact the appearance of the status bar but rather the system UI visibility. As a result, the derived mask from system bars appearance would be 0 since both the activity and dialog would have appearances of 0. Rather than try and "future-proof" this implementation for other uses of system bar appearance, this change is directed only at updating the `APPEARANCE_LIGHT_STATUS_BARS` bit in the dialog's system bar appearance. The only other native code that touches status bars is the `StatusBarModule` and that only touches this flag. This is a follow-up to https://github.com/facebook/react-native/issues/34899. ## Changelog: <!-- Help reviewers and the release process by writing your own changelog entry.

React Native

React Native brings React's declarative UI framework to iOS and Android. With React Native, you use native UI controls and have full access to the native platform.
- Declarative. React makes it painless to create interactive UIs. Declarative views make your code more predictable and easier to debug.
- Component-Based. Build encapsulated components that manage their state, then compose them to make complex UIs.
- Developer Velocity. See local changes in seconds. Changes to JavaScript code can be live reloaded without rebuilding the native app.
- Portability. Reuse code across iOS, Android, and other platforms.
React Native is developed and supported by many companies and individual core contributors. Find out more in our ecosystem overview.

📋 Requirements
React Native apps may target iOS 13.4 and Android 5.0 (API 21) or newer. You may use Windows, macOS, or Linux as your development operating system, though building and running iOS apps is limited to macOS. Tools like Expo can be used to work around this.
🎉 Building your first React Native app
Follow the Getting Started guide. The recommended way to install React Native depends on your project. Here you can find short guides for the most common scenarios:
📖 Documentation
The full documentation for React Native can be found on our website.
The React Native documentation discusses components, APIs, and topics that are specific to React Native. For further documentation on the React API that is shared between React Native and React DOM, refer to the React documentation.
The source for the React Native documentation and website is hosted on a separate repo, @facebook/react-native-website.
🚀 Upgrading
Upgrading to new versions of React Native may give you access to more APIs, views, developer tools, and other goodies. See the Upgrading Guide for instructions.
React Native releases are discussed in this discussion repo.
