The block endpoint returns block id / prev / timestamp nested under a
"header" object with camelCase keys (blockId, dcId, prevId, prevProof,

Block fields never matched the response and always deserialized empty.
Add a BlockHeader interface, nest it in Block, and make proof.scheme
optional. Verified live against a dev chain.
