feat(openmetadata): direct-API enrichment for real sample data, profiles & end-to-end lineage

OM connectors/profiler stored data but its denormalized read path left
Sample Data/Lineage tabs effectively empty. This script populates OM directly:
- real 50-row sample data for source + iceberg curated tables
- table/column profiles (column profiles read back correctly in UI)
- full traceable lineage: generator -> source -> Debezium/Kafka CDC topic
  -> S3 archive + Iceberg curated -> Trino query layer
