Subject: [PATCH] rpc: add blockAccessListHash to RPC block header response
 (#33994)

Adds support for returning `blockAccessListHash` in the RPC block header
response.

This change includes `blockAccessListHash` in `RPCMarshalHeader` when
`head.BlockAccessListHash` is not nil, aligning the RPC output with the
Header struct which already contains this field.
