Change the Status Bar Color on iOS and Android in a PWA

The default status bar color on iOS doesn't look great with the color scheme of our application, so we'll set a custom theme color for Android, and a status bar meta tag for iOS. We can't set a fully custom status bar color in iOS, but we can set the apple-mobile-web-app-status-bar-style meta tag to either default, black, or black-translucent.
