Fix screenshot prevention on iOS

[GianniCarlo]

Bugfix

• Fix screenshot prevention on iOS 17 not working

Related issues

#28

Approach

• Update enableSecureView to create the textfield, and then add the layer to the keyWindow layer, which should be outside the RN rendering cycle
• Update disableSecureView to remove the textfield layer from the window layer

Things to be aware of / Things to focus on

• In my workplace we only needed the screenshot prevention feature to work, so I removed the image functionality, but this could be the proof of concept needed, as I think we can just add the image as a background to the textfield and it should work
  • I did test that we can show a different color for the background
