blockchain_test_engine bugs in tests-focil-devnet@v0.2.0: BAL validation vs gasLimit failure

"tests/frontier/validation/test_transaction.py::test_tx_gas_limit[fork_Bogota-blockchain_test_engine_inclusion_list]"

The BAL contains 19 storageReads+storageChanges. Add with the BAL items len(6) = 25

The block `gasLimit` is only 21000, divided by BAL_ITEM_COST 2000, the max cap of BAL item limit is 10.

So BAL item exceeds max items cap. 25 > 10. But the fixture expect no validationError where is should have.

Start with tests/frontier/validation/test_transaction.py::test_tx_gas_limit[fork_Bogota-blockchain_test_engine_inclusion_list] and reproduce the failure in the tests-focil-devnet@v0.2.0 fixture. Trace how the BAL item count and gasLimit are validated, then verify that the fixture's expected validationError matches the resulting behavior.
