What this PR does / why we need it:

This PR enhances the Feast OpenLineage integration to provide comprehensive, production-ready lineage tracking across all Feast objects and interaction paths.

  • Full object coverage in lineage: Extends lineage support beyond Feature Views and Feature Services to include SavedDatasets, On-Demand Feature Views, Entities, and DataSources - both in the OpenLineage graph and in Feast-only registry lineage. SavedDatasets now show connectivity to their upstream FeatureService, FeatureViews, and DataSources via storage matching.

  • Richer OpenLineage UI: Adds producer-based color coding, Feast type filtering, directional focus-on filtering (upstream + downstream without cross-branch bleed), node subtitles showing source type, detailed data source metadata in the side panel (path, table, query, timestamp fields, field mappings), and a toggle that auto-defaults to Feast-only lineage when no OL events exist yet.

  • API and registry sync: Wires OpenLineage emission and cleanup into the RegistryServer layer so that objects created, edited, or deleted via REST API / gRPC (not just feast apply) are immediately reflected in the lineage graph. Adds delete_dataset and delete_job store methods for clean removal.
