test_invalid_post_fork_block_without_slot_number()

Documentation for tests/amsterdam/eip7843_slotnum/test_fork_transition.py::test_invalid_post_fork_block_without_slot_number@26332146.

Generate fixtures for these test cases for Amsterdam with:

fill -v tests/amsterdam/eip7843_slotnum/test_fork_transition.py::test_invalid_post_fork_block_without_slot_number --fork Amsterdam

Reject an activation block whose header lacks the slot_number field.

From the fork activation onward the field is mandatory: a header without it is malformed and the engine payload is missing a parameter required by its version.
