DESCRIPTION >
    Hourly aggregates WITHOUT properties for fast aggregation queries.
    Fresh backfill of events_hourly_no_properties_mv after cleanup.
    Drops the properties column from the GROUP BY so rows with different
    properties but the same (org, env, customer, event, entity, hour)
    are collapsed into a single row.
