AI Summary: The task is to fix a bug in the Cow Protocol Services e2e tests where wallets cannot be funded with ETH when a forked test is created without specifying the fork block number. This requires modifying the e2e test code to ensure that accounts are properly funded with ETH before tests involving transactions are executed, likely by adding a funding step that explicitly sends ETH to the necessary accounts using the provided RPC connection to the forked blockchain.

AI Summary: Debug and fix a bug in the Cow Protocol Services e2e tests where fetching UniV3 liquidity fails when using a forked node with a pinned block. The issue occurs specifically in the `quote_verification.rs` test file and prevents proper testing of UniV3 support in the baseline solver. The solution requires investigating why liquidity fetching fails with a pinned block but works without it, and modifying the test or the liquidity fetching logic to resolve the discrepancy.
