test_block_regular_gas_limit()

Documentation for tests/amsterdam/eip8037_state_creation_gas_cost_increase/test_state_gas_reservoir.py::test_block_regular_gas_limit@87aba1a3.

Generate fixtures for these test cases for Amsterdam with:

fill -v tests/amsterdam/eip8037_state_creation_gas_cost_increase/test_state_gas_reservoir.py::test_block_regular_gas_limit --fork Amsterdam

Test check_transaction enforcement of regular gas against block limit.

The regular gas check uses min(TX_MAX_GAS_LIMIT, tx.gas). Fill the block with transactions at TX_MAX_GAS_LIMIT and verify the last one is accepted or rejected based on remaining capacity.
