fix(lineage): prevent pipeline annotation inheritance in service/domain/dataProduct lineage and add pipeline service edges

Bug #1: Service nodes (e.g., DatabaseService, MessagingService) were incorrectly appearing in
entity-level lineage views. Root cause: getOrCreateLineageDetails() in addServiceLineage(),
addDomainLineage(), and addDataProductsLineage() was copying the pipeline annotation from
entity-level LineageDetails to service/domain/dataProduct-level LineageDetails. This caused
service entities to have upstreamLineage.pipeline.fqnHash set in their Elasticsearch documents,
making them match the PIPELINE_AS_EDGE_KEY query during BFS traversal and incorrectly appear
alongside actual data assets. Fix: add .withPipeline(null) on each service/domain/dataProduct
LineageDetails object to strip the pipeline annotation before persisting.

Bug #2: "By Service" view was empty when viewing lineage for pipeline entities that were stored
as edge annotators (Case B: table → topic with pipeline=flink_pipeline in LineageDetails) rather
than as actual nodes (Case A). Root cause: addServiceLineage() only created database_service →
kafka_service edges but no edges involving flink_pipeline_service. Fix: add addPipelineServiceEdges()
called from addServiceLineage() that creates fromService → pipelineService and pipelineService →
toService edges when a pipeline annotation exists in the entity-level lineage details.

Also add unit tests covering both fixes to prevent regression.
