Transformers - Materialize APR tables

[marcus-snx]

Streamlit is querying the APR views, and due to the WHERE combined filter on timestamp and pool_id the query plan selects a very slow path.

Solution:

• materialize the views as tables (removes the nested loop due to the complicated JOINs in the view)
• drawback: doubles the dbt run time (which right now is quite fast so it's not an actual problem for the time being

Another possible solution is to try and 'fool' the query planner to first filter solely on timestamp or pool_id (which is fast even with a view).
