# Description
Decouples Churn/Account Margin model of `int_monthly_aggregated_metrics_history_by_deal_by_time_window` from the model `int_monthly_aggregated_metrics_history_by_deal`.
Changes:
* Removes dependency and reads from KPIs models.
* Removes unused deal stage variable
* Jinja template for time windows with dynamic selection to DRY
This has been tested with dbt audit tools and the md5 for pure refactoring, so output is exactly the same.
