feat(relayer): Withdrawals root

[cyberhorsey]

This PR fixes the remaining bridge issues for claiming messages.

1. post-shanghai forks need withdrawalsRoot for generating proofs. This is why neither relayer nor bridge-ui work on Sepolia right now, but work on internal devnet, hardhat tests, and Goerli. But code must be backwards compatible with non-shanghai chains. Now this proof generation works on both.

2. Ethers can not process empty string for bytes or bytes32, so with relayer-saved transactions from the API, we need to check if Message.Data is empty, and if so, set it to 0x, which ethers accepts.

3. Working in this project doesnt feel good with adding very strict eslint and then not fixing any of the issues. I removed ESLint, and we can re-add a light one, and fix rules one by one, so its a happy working environment. There is no value to the current approach at all.

4. Update go-ethereum library to latest, so we have access to WithdrawalsHash on the header, for post-Shanghai forks such as Sepolia.

5. Add code coverage for both types of blocks.

6. bridge UI was using the MySQL database ID and not the message ID, so claim header hash would not be valid.

After merging this, bridge-ui will auto deploy to Vercel, but relayer needs deployment in Kubernetes after latest image builds.
