refactor: make checking balance just use web3.js scripts, rather than having them build a react app. We still cover react in the 'interact with wallets' lesson, we're just focusing more on Solana itself this early.
refactor: split 'writing data' lesson into two lessons with separate labs - one for transferring sol (with a lab), one for learning how to create instructions for arbitrary apps
