feat(etl): Hadoop->Trino movement DAG + movements registry + autonomous ETL-agents

- DAG hadoop_to_trino (deployed to Airflow) + worker hadoop_to_trino.py (on the
  Hadoop master) move HDFS historical_sales -> iceberg.hadoop.historical_sales_hdfs.
- api/movements.py: movement registry, Airflow trigger+watch, run tracking
  (state/duration/rows), endpoints /api/movements, /{id}/run, /runs.
- agent_ops.py: ETL-agent loop autonomously triggers movements on an interval
  and logs each run; /api/agent-ops/etl/toggle + etl status.
