feat(tests): EIP-8037 base fee follows the bottleneck gas dimension

[chfast]

🗒️ Description

Add a two-block test asserting the child block's base_fee_per_gas is driven by the parent header gas_used = max(block_regular_gas_used, block_state_gas_used).

Block 1 is pushed above the gas target by a single dimension (state via spilling SSTORE-set txs, or regular via STOP txs) while the other stays below it, so the dominant dimension alone decides whether the child base fee rises. Block 2 is empty and its base_fee_per_gas must equal the EIP-1559 update fed block 1's max-dimension gas_used.
