test_invalid_pre_fork_block_with_bal_hash_field()

Documentation for tests/amsterdam/eip7928_block_level_access_lists/test_fork_transition.py::test_invalid_pre_fork_block_with_bal_hash_field@622620d8.

Generate fixtures for these test cases for Amsterdam with:

fill -v tests/amsterdam/eip7928_block_level_access_lists/test_fork_transition.py::test_invalid_pre_fork_block_with_bal_hash_field --fork Amsterdam

Reject a pre-Amsterdam block whose header carries block_access_list_hash.

The engine fixture sends a pre-Amsterdam newPayload carrying an empty blockAccessList param; the client's reconstructed header omits the hash, so the block hash check fails.
