Issue:
For the StatusBar component, it seems that we are currently only accepting integer values for color, and not PlatformColor values from Android.

You can see the relevant code here:

react-native/packages/react-native/Libraries/Components/StatusBar/StatusBar.js

Line 450 in 85bdd75

invariant(

When a PlatformColor is passed, processedColor becomes an object, which causes an error. This behavior appears to be intentional, but the exact reason for not supporting PlatformColor is unclear.

Proposed Solution:
We can use ColorPropConverter.getColor, which parses PlatformColor values correctly. However, for this solution to work, we would also need to update StatusBarModule to accept these values as valid inputs.

@cortinico , what are your thoughts on this approach?
