[MDS-6227] Add administrative amendments and filter to now_gis_export API

[taraepp]

Objective

• remove the filtering out of administrative amendments from now gis view
• add it as a column in the view, so it can be filtered for
• add it as a parameter on the now gis endpoint

MDS-6227

Testing considerations

• the automatic tests that I added can only look at the status code of the response, once you try to look at the data everything kind of falls apart because the view depends on tables that don't exist in the test context
• so it was all tested manually/locally

1. changed 2/800 now_application_identity records to have an application_type_code of ADA instead of NOW
2. recreated the view locally (basically ran the migration in Postico, taking out materialized, with data, and TABLESPACE pg_default, and simplified the first statement to just a DROP VIEW)
3. added a console log in now_application_gis_export_resource.py-> get-> generate (logged r)
4. made a call in postman to http://localhost:5000/exports/now-application-gis-export?application_type_code=ADA and watched the logs in core-api container (postman can't easily handle streaming responses and so only the header is visible!)
5. Saw that the two results (and only the two results) that I had changed to ADA were logged

Yay more tests!

Everything looks solid to me. Always a little bit annoying working with the stuff that only exists in Prod.
