Merged PR 4757: Creates a Total Booking Fees metric (Old dash + New dash)

# Description

Main Changes:
* Computes the total booking fees in `int_kpis__metric_daily_invoiced_revenue`
* Propagates within KPIs, including schema and tests
* Propagates within cross in both "by deal" and "by dimension/global"
* Propagates to main kpis tests

Small fix:
* In `int_mtd_vs_previous_year_metrics`, manual formatting because sqlfmt is broken on this model...
