Complete and document DB load into Dev instance

[regetz]

Work here is to complete the loading of the VegBank DB snapshot into the Postgres DB instance running in our K8s dev environment, and then commit documentation for all steps to the repo.

The docs should fully and accurately cover the steps starting with a dumpfile of the original VegBank DB, and ending with having it loaded into a fresh Postgres instance deployed to K8s. We should be able to use this documentation to repeat this process in the future when it's time to deploy to Production -- or possibly do again in Dev if we never want/need to rebuild from scratch for some reason.
