test_legacy_initcode_eof_contract_fails()

Documentation for tests/osaka/eip7692_eof_v1/eip7620_eof_create/test_legacy_eof_creates.py::test_legacy_initcode_eof_contract_fails@bc691d13.

Generate fixtures for these test cases for Osaka with:

fill -v tests/osaka/eip7692_eof_v1/eip7620_eof_create/test_legacy_eof_creates.py::test_legacy_initcode_eof_contract_fails --fork Osaka

Verifies that legacy initcode cannot create EOF.

This tests only ensures EIP-3541 behavior is kept, not altered by EIP-7620.
