Manual testing steps

Prerequisite: Open file, app/components/UI/Earn/constants and change USER_HAS_LENDING_POSITIONS to equal true. The buttons will only appear if the user has existing lending positions. This temp variable simulates this.

1. From the token list (home screen) click on a supported stablecoin (DAI, USDC, USDT)
2. On the asset overview page, you should see the withdraw and deposit more buttons
3. Clicking withdrawal should redirect you to the withdrawal input screen
4. Clicking deposit more should redirect you to the deposit input screen
