PR Summary

Medium Risk
Introduces a new RPC path that parses raw starknet_getBlockWithTxs responses and extracts transaction_hash from JSON, which may be brittle across node implementations but doesn’t touch consensus, auth, or persistent state.

Overview
Adds support for fetching a block header and full transactions in a single RPC call by introducing GetBlockWithTxsParams/BlockWithTxs and a new RpcStateReader::get_block_info_with_txs helper.

Updates RPC HTTP tests to cover the new method and validate that returned transactions include an expected TransactionHash for a known block.
