VPN-2387: Fix iOS status bar color on iOS 16

[mcleinman]

Description

This ended up being a bug on iOS 16 only, so the fix only affects iOS 16 and below. Somehow the status bar type is getting reset to default, causing the issue here. I checked all the places our code resets it to default, and it didn't seem to be happening in any of those spots - so I made this fix.

Once our minimum iOS version is iOS 17, we can remove this code - and I've left notes in the code that remind us of this.
