[native] Fix LoggedOutModal buttons not appearing on load in release build

Summary:
This resolves ENG-8321.

I made a mistake in D12208. In Reanimated 3 it's okay to pass a Reanimated value directly to a style prop of an Animated.View, but not in Reanimated 2. I had been reading the Reanimated 3 docs initially, and after learning about this I updated most places but seem to have missed this spot.

In Reanimated 2, all uses of Reanimated values must be wrapped in useAnimatedStyle.

Guessing it only shows up in a release build due to some race conditions.

Test Plan: Confirmed that it resolves the linked Linear issue by compiling a release build to my iOS simulator
