Merged PR 3482: Adapts date dimension skeleton for Main KPIs

# Description

New model:
* int_kpis__agg_dates_main_kpis - Serves as the skeleton of dates and dimensions for Main KPIs. It's aggregated since it follows a similar aggregation strategy. It's a single model to feed both Main KPIs visualisations. Note boolean fields are real booleans (true/false) while before these were integers (1/0). This also affects downstream models.

Main KPIs flow adaptations to new skeleton model:
* int_monthly_aggregated_metrics_history_by_deal
* int_monthly_churn_metrics - additionally, calls usual KPIs macro instead of old one
* int_mtd_vs_previous_year_metrics

Reporting changes to ensure report is not down:
* mtd_aggregated_metrics - adaptations on booleans (true-1, false-0)

Cleaning:
* get_kpi_dimensions macro is no longer used
* int_dates_by_deal model and schema entry
* int_dates_mtd_by_dimension model and schema entry
* int_dates_mtd model and schema entry
