* chain/ethereum: add json_patch module for unified type field patching Add a dedicated module for JSON patching utilities that handle missing `type` fields in Ethereum transactions and receipts. This consolidates patching logic that will be used by both the HTTP transport layer (for RPC responses) and cache deserialization (for stored blocks). The module provides: - patch_type_field: Adds "type": "0x0" to JSON objects missing the field - patch_block_transactions: Patches all transactions in a block - patch_receipts: Patches single receipts or arrays of receipts * chain/ethereum: refactor PatchingHttp to use json_patch module Refactor the HTTP transport's receipt patching to use the shared json_patch module instead of duplicating the patching logic. This removes the patch_receipt and patch_result methods from PatchingHttp and replaces them with calls to json_patch::patch_receipts. The patch_rpc_response and patch_response methods remain as they handle RPC-specific JSON-RPC response structure. * chain/ethereum: patch missing type field in cached blocks Add patching for cached blocks before deserialization to handle blocks that were cached before March 2022 when graph-node's rust-web3 fork didn't capture the transaction type field. This patches transactions and receipts in cached blocks at two locations: - ancestor_block(): For full block deserialization (EthereumBlock), patches both transactions and transaction_receipts - parent_ptr(): For light block deserialization (LightEthereumBlock), patches only transactions (light blocks don't include receipts) The patching adds type: 0x0 (legacy) to transactions/receipts missing the field, allowing alloy to deserialize blocks that would otherwise fail due to the missing required field. * chain/ethereum: add EthereumJsonBlock newtype for cached block handling Introduce EthereumJsonBlock newtype with helper methods for format detection (is_shallow, is_legacy_format) and deserialization (into_full_block, into_light_block). Cleans up repeated logic and avoids unnecessary clones by taking ownership of the JSON data. * chain/ethereum: use concrete types in EthereumJsonBlock methods Remove generic type parameters from into_full_block() and into_light_block(), returning EthereumBlock and LightEthereumBlock directly instead. * chain/ethereum: add doc comments to EthereumJsonBlock methods * chain/ethereum: remove unused From<Value> impl for EthereumJsonBlock
