Agent now uses Camel processorId as RouteNode.id, eliminating the nodeId mapping layer. Drop diagram_node_id column (V6 migration), remove from ProcessorRecord/ProcessorNode/IngestionService/DetailService, add /processor-routes endpoint for processorId→routeId lookup, simplify frontend diagram-mapping and ExchangeDetail overlays, replace N diagram fetches in AppConfigPage with single hook.
