Subject: [PATCH] feat: default Block param to 'latest' on eth_* state methods

Mark the Block param required: false (default 'latest') on the six
state-reading methods in state.yaml: eth_getBalance, eth_getStorageAt,
eth_getStorageValues, eth_getTransactionCount, eth_getCode, eth_getProof.

Mirrors the eth_simulateV1 idiom (description "default: 'latest'") since a
bare default: keyword sibling to $ref is ignored by JSON-Schema tooling.

Spec-only. Conformance fixtures (tests/*.io) are generated by rpctestgen
against go-ethereum and cannot be filled until geth implements
default-to-latest; per CONTRIBUTING the behavior must land in go-ethereum
first. Proposal for discussion at RPC Standards (ref NethermindEth/nethermind#11764).
