[PULL REQUEST] Update Estimates to allow for Series 16 MGRAs

[GregorSchroeder]

Describe this pull request. What changes are being made?

• This pull request prepares the employment module to use Series 16 geographies by pulling directly from the [inputs].[mgra] table within the sql/employment/get_military_employment.sql and sql/employment/xref_block_to_mgra.sql SQL scripts.

• Special MGRAs for Series 16 are added.

Validation and testing

Ran employment module in debug mode for [run_id] =233 successfully.
@SarahHudson-SANDAG visually confirmed Series 16 special MGRAs in ArcGIS Pro.
Ran a full 2020-2025 test run using Series 16 with the special MGRAs inserted into production ([run_id]=234) and it passed all reporting/reporting.py checks.

What issues does this pull request address?

closes #296
closes #297

Additional context

The two SQL scripts were originally written to only run on the GIS server due to a double-hop issue that has since been resolved by the IT team. This was the only part of the Estimates Program besides adding special MGRAs (see #296) that would not work with Series 16 MGRAs.

@bryce-sandag - please review SQL+Python+outputs
@gracechung - please review the Series 16 special MGRAs

sql/employment/xref_block_to_mgra.sql:22

• The new run_id-based lookup makes this cross-reference work with the run's MGRA series, but the file header still states that it maps only to Series 15. Update the header so future callers are not given an obsolete constraint.

DECLARE @run_id INTEGER = :run_id;

I have reviewed the Series 16 special MGRAs and confirmed that the list includes all prisons and detention facilities. The assigned/tagged MGRAs (MGRA16) are correct.
