This PR will compute the listing metrics in an aggregated manner to be displayed in the Main KPIs dashboard, specifically:
- New Listings
- First Time Booked Listings
- Churning Listings
- It also adapts the computation for the already existing metrics of Listings Booked in X months
At code level, it contains the following:
- Adds `int_core__mtd_accommodation_metrics`, which computes the aggregation of the lifecycle of listings at date level (unique), being date the corresponding date from `int_dates_mtd`
- Changes `int_core__mtd_aggregated_metrics` to take the accommodation metrics from the new model. Those 3 already existing (Listings booked in X month) now read from the new model as well.
- Changes `int_core__mtd_booking_metrics` to remove unused computation, making it lighter. Specifically, it removes 1) listing related metrics, since now we have a dedicated model and 2) number of guests booked, since it's not used at all.
The resulting values in local are consistent with what is already reported in the staging report.

Adding int_core__accommodation
Includes both:
- Main information of the accommodation, mostly coming from stg_core__accommodation and int_core__country.
- Listing lifecycle computation, based on the created bookings from stg_core__bookings. It's just the current state, no history.
Some considerations:
- I opted to use stg_core__bookings and not int_core__bookings. Main reason is in case at some point we want to add listing-based information to the booking table, it would avoid cyclic references.
- I opted to keep all the logic of 1) accommodation info and 2) lifecycle in the same model. This could be easily split into: lifecycle first that reads uniquely from staging and then the int_core__accommodation that could read from the staging version to retrieve accommodation attributes + the lifecycle one. Up to you
I'd suggest to review first the documentation in schema since it explains the logic applied.

Adding Country to intermediate, both model + documentation.
At this stage, the model is set as a view but we can discuss what is the best approach

Adding cancelled bookings metric based on the feedback of the tech team. Mainly, the date of a cancelled booking can be considered as the `updated_date_utc` for those bookings with status cancelled, as it's a terminal state and no additional steps should follow.
I also took the opportunity to update:
- The order on the `int_core__mtd_aggregated_metrics`, so it matches the one in the Notion page for the 1st batch, freeing already the space for the order_by numbers for missing metrics
- Make acronyms of alias in the `main_kpi` subquery in `int_core__mtd_booking_metrics` slightly more clear
- Remove empty line at the end of the file in `int_core__mtd_booking_metrics`
Keep in mind that the cancelled bookings metric will be directly available in the dashboard once this PR is approved and DWH re-runs.

The CTEs that project currency rates backwards have a few mistakes that introduce additional dates in the period where we do have actual, factual rates. This PR fixes the errors that cause this.
