Merged PR 3578: First version of int_core__booking_service_detail

# Description

Minor Changes:
* Computation in staging of `is_default_service` column for Basic Screening. This includes `stg_core__product_service`, `stg_core__protection_plan` and the schema entry.
* Propagation of `is_default_service` to intermediate. This includes `int_core__protection_plan_to_price`, `int_core__product_service_to_price` and the schema entry.
* Adapting a small data test to include a new case in `stg_core__booking_view_to_service` schema entry.

Main Changes:
* New fields and re-order existing ones on `int_core__booking_to_service`.
* Changed materialisation of `int_core__booking_to_service` to a view, since the new model `int_core__booking_service_detail` is materialised as table.

New Model:
* First version of `int_core__booking_service_detail`. This model includes the current state of a Service that is applied within a Booking. It includes many Booking attributes, Service attributes as well as some meta data fields regarding the business scope and type, according to the [New Pricing](https://www.notion.so/knowyourguest-superhog/All-Services-Definitions-333fba1fbed54715b6b1c3b5133f0d4f) documentation.
* This is one of the 3 Booking models that I propose to create for New Pricing. You can read about the others [here](https://www.notion.so/knowyourguest-superhog/Services-and-Revenue-modelling-1420446ff9c980118e0cfffa7c41f369), although I'll probably won't do them until New Dash is finalised on tech side.
* This current model should suffice to be able to understand which services are applied within a Booking. Notably you will see that this is not enough to compute revenue, as there's some placeholders in place. This is expected.
