bug(android): navigation bar not always styled correctly

Following edge-to-edge work #14396 and #14934

The navigation bar is not always styled correctly. Text can still show behind it.

Using a Keyman keyboard shows the text behind the navigation bar:

Using Google's gboard shows the navigation bar with black background:

Couple questions:

• Is that happening in all apps?
• What version of Keyman are you on?
• What version of Android is your device?

On my Android 16 device I'm getting a black nav bar across the apps

That's with Keyman 19.0.196-alpha on Android 15.

It looks like it's happening in all apps, although it's not visible in all apps because they change the content if the keyboard gets activated. E.g. in a message in Slack shows a (empty) textbox at the bottom. However, on the Search in Slack I see it: without keyboard I have a long list channels that fills more than the entire screen. If I click in the search field it shows the keyboard on top of the list:

Another example where I see it is in the search in Messages: if I select one of the categories (e.g. Unread) that show more than a screen of messages the keyboard is displayed on top of the messages (see screenshots in the description).
