Merged PR 4400: Adds Billable Bookings split per scope

# Description

Changes:
* Adds Business Scope split on Billable Bookings + propagates towards Agg/Metric Monthly/MTD models

- [X] The edited models and dependants run properly with production data.
- [X] The edited models are sufficiently documented.
- [X] The edited models contain PK tests, and I've ran and passed them.
- [ ] I have checked for DRY opportunities with other models and docs.
- [ ] I've picked the right materialization for the affected models.

# Other
