Generate fixtures for these test cases for Amsterdam with:

fill -v tests/amsterdam/eip7708_eth_transfer_logs/test_transfer_logs.py::test_inner_call_succeeds_outer_reverts_no_log --fork Amsterdam

Test that logs from successful inner calls are rolled back on outer revert.

Scenario: Contract performs N CALLs with value (all succeed), then REVERTs. Expected: No logs remain (all transfer logs are rolled back).
