Migrate vista precinct script to open source dependencies

[stdavis]

This has not been fully tested on the vista servers yet so I don't want to merge this. But I did want a review.

Pull request overview

This PR migrates the Vista precinct update/export tooling away from ArcPy/ODC-based workflows to an open-source, Conda-managed Python stack (GeoPandas + SQLAlchemy), with supporting docs and developer ergonomics.

Changes:

• Replaces legacy ArcPy precinct export/update scripts with a new UpdatePrecinctID.py that queries Oracle + PostGIS and performs a GeoPandas spatial join.
• Adds a Conda environment definition, sidecar JSON config template, a “tracer bullet” connectivity script, and pytest coverage for key helpers/output formatting.
• Removes several ArcPy-based checker/update scripts and an exported CSV artifact; updates repo ignore rules and VS Code settings for the new workflow.

I appreciate the effective documentation in the README. The try-catch around imports is also a good practice. New script additions and old script removals look good as the project is migrated. Approved.
