Generate fixtures for these test cases for Amsterdam with:

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

Test that CREATE with insufficient balance does NOT emit transfer log.

Contract receives 1, tries to CREATE with 1000 value - CREATE fails (returns 0) but doesn't halt, so tx-level log remains.
