feat(openmetadata): ingest Elasticsearch (search) + Airflow (pipelines)

- ES: connect over https with verify_certs=false (self-signed CA); 16 indexes incl source_data
- Airflow: ingest 8 DAGs as pipelines from SQLite metadata DB snapshot
- es_run.py: standalone runner that pins the working ES TLS config
- Command Center API now wired with ELASTIC_PASSWORD
