Optimize log filter matching and trigger allocation (#6419)

* chain/ethereum: Use O(1) edge lookup in EthereumLogFilter

Replace all_edges() linear scan with contains_edge() and edge_weight()
in matches() and requires_transaction_receipt().

* chain/ethereum: Pre-allocate triggers Vec in parse_log_triggers

Replace flat_map(...).collect() with explicit loops and a pre-sized Vec
to avoid repeated reallocations.

…ted memmove

Replace flat_map(...).collect() with explicit loops and a pre-allocated
Vec. FlatMap size_hint returns (0, None), so collect() starts with a
small buffer and doubles repeatedly, triggering memmove to copy the
growing buffer on each reallocation.

For high-activity blocks with thousands of logs, this caused
__memmove_avx_unaligned_erms to consume ~17% of total CPU time.
Pre-counting logs and using Vec::with_capacity eliminates all
reallocations.

…ization (#6400)

* graph, chain/ethereum: Move json_patch and json_block modules to graph crate

Move EthereumJsonBlock and JSON patching utilities from chain/ethereum to
graph/src/components/ethereum/ so they can be used by the store layer
without circular dependencies. This prepares for typed block caching where
CachedBlock::from_json() needs access to these utilities.

* graph: Add CachedBlock enum and typed block cache

* graph, chain/ethereum, store: Address review feedback

- Return Arc<LightEthereumBlock> from into_light_block() to avoid deep clone
- Move cache_block_to_block_ptr_ext into CacheBlock::to_extended_block_ptr()

chain/ethereum, graph: Replace AnyNetwork with AnyNetworkBare to remo…

…ve WithOtherFields overhead (#6398)

AnyNetwork wraps every RPC response (block, transaction, receipt) in
WithOtherFields<T>, which uses #[serde(flatten)] to capture unknown JSON
keys into a BTreeMap. This forces serde to buffer entire JSON objects
into intermediate Value maps and re-serialize them to diff keys on every
block and every transaction. graph-node never reads these extra fields.

Define AnyNetworkBare, a custom Network impl that uses the same
AnyTxEnvelope/AnyReceiptEnvelope types (for L2/sidechain tx support)
but without the WithOtherFields wrapper on response types. This
eliminates the flatten buffering, BTreeMap allocation, and
re-serialization from the deserialization hot path.
