## What? * Optimizes funding by using `anvil_setBalance` - this makes anvil generate no blocks during funding resulting in smaller state * Fixes a bug where rich account was only funded with 0.01 ETH as the default got changed on server side * Adds support for new server layout (with manually compressed anvil state). See matter-labs/zksync-os-server#837 <!-- Briefly explain what this PR does. --> ## Why? <!-- Briefly explain why this PR does it. Specify the reason of the changes. --> Needed to unblock gateway integration + get rid of hacks introduced because anvil did not support historical blocks during `eth_call` --------- Co-authored-by: Anton Baliasnikov <[email protected]>

Summary
Alternative to #846 that uses compressed
l1-state.json.gzfiles with stable anvil. Just to be clear: the state format is not supported by anvil 1.5.1, so I updated scripts and guides to reflect that. This might affect development short-term as you can no longer spin-up anvil in a single command.L1 state was generated using matter-labs/zksync-os-scripts#11, which:
draft-v31-with-zksync-osbranchAlso includes minor refactoring of integration tests as I had to touch L1 initialization logic.
