Generate fixtures for these test cases for Amsterdam with:

fill -v tests/amsterdam/eip7928_block_level_access_lists/test_block_access_lists_eip4895.py::test_bal_withdrawal_and_value_transfer_same_address --fork Amsterdam

Ensure BAL captures both value transfer and withdrawal to same address.

Alice starts with 1 ETH, Bob starts with 0. Alice sends 5 gwei to Bob. Bob receives withdrawal of 10 gwei. Bob ends with 15 gwei (5 from tx + 10 from withdrawal).
