Updates the Block Access List index type from
uint16touint32across the entire stack to future-proof the BAL for higher gas limits (300M+) andEIP-2780compatibility. The current uint16 index caps out at65,535entries per block, which is insufficient once gas limits scale beyond current levels. Widening touint32eliminates this ceiling entirely, ensuring the BAL remains viable without further type migrations as the protocol evolves.Spec Change Refrence: ethereum/execution-specs#2713
