fix(earn): entry point performance and ripple (#6252)

### Description

- Sets the ripple above the image on Android to be consistent with other
items on the screen.
- Uses
[`react-native-fast-image`](https://github.com/DylanVann/react-native-fast-image)
to display the background image for better performance.
