Mobile app dark theme respect system dark theme toggle
iOS and Android both have native system dark themes now. The Teams app should respect the system dark theme toggle like the Outlook mobile app does. Eg when the system dark theme is activated, the Teams dark theme should be automatically be activated and vice versa.

When dark mode is activated in Teams, the loading screen should be dark (black) not white.
The Teams iOS app should not require a restart (close/re-open) to switch from light to dark mode and vice versa. The rest of the Microsoft Office iOS apps can dynamically switch between the light and dark themes without a restart.
