refine_to_hive_hourly: Switch from staging to production

Update refine_to_hive_hourly DAGs to use production settings instead of staging:

• start_date
• output_database
• output_tables_base_location
• diff_database
• Remove "staging" tag from DAG tags

And update tests.

This change transitions the refine_to_hive_hourly DAGs from staging configuration to production configuration, ensuring data is written to the production event database and compared against the event_systemd database.

!1550 (merged) is required first.
