Preserve EIP-2930 access-list entries through Ethereum decoding, signature reconstruction, JSON, and Casper binary serialization. Append the new binary fields so older transactions continue to decode. Expose Prague intrinsic-gas calculation so node admission can account for the upfront cost introduced by an access list.
Translate access-list addresses and storage keys into the revm transaction environment so Prague execution applies intrinsic charges and warms the declared state. Cover EIP-2930, EIP-1559, and EIP-7702 transactions, including the observable storage-read gas reduction.
Account for access-list prepayments during node admission so a newly supported non-empty list cannot make revm reject the transaction during block execution. Return a dedicated binary-port error for the intrinsic-gas shortfall and document the access-list validation behavior.

This PR adds end-to-end support for EVM transaction access lists.
Access lists let a transaction declare the accounts and storage keys it expects to use. The transaction pays the access-list cost upfront, and those entries are treated as warm during execution. This can reduce execution gas when the declared state is accessed enough to offset that upfront cost.
The change:
