Ignore Dark Mode setting on iOS13

[errorists]

Problem

At present, whenever dark mode is enabled on iOS, it only introduces a bunch of bugs without any advantages.

• Status bars are presented white making them invisible against our white backgrounds,

• photo picker dialogues are presented with incorrect styling all over, making them difficult to use

• dark keyboards are an unwelcome sight without a Dark Mode of our own.

Implementation

To quote the maestro @flexsurfer

it seems like simple one to ignore dark mode
add this to your Info.plist file:
UIUserInterfaceStyle
Light

Acceptance Criteria

There are no visible changes to our UI when dark mode is enabled.

thank you kindly! 🙏
