Merged PR 4423: Logic for Billable Bookings in New Dash Bookings

# Description

Changes:
* Tags services to be billed (invoiced to host) in the staging models of product_service and protection_plan
* Propagates into booking_service_detail master table. This also computes billable dates.
* Propagates into booking_summary master table. This has the final determination of a booking being billable or not, and when the first and last billing should occur.

# Checklist

- [X] The edited models and dependants run properly with production data.

- [X] I have checked for DRY opportunities with other models and docs.
