Prototype postgREST for datastore API

[jduss4]

@mogul recommended that we look into using postgREST for our backend API server. Let's evaluate what it does, how it might be used, and what benefits / downsides it might have if we incorporated it into our application.

Acceptance criteria:

• We have prototyped with using postgREST with a postgres database
• Lessons from the prototype process have been incorporated into the datastore ADR

You may want to grab a little of Matt Jadud's time for a crash introduction and to see what he's learned based on using it for the FAC. One of the companies sponsoring PostgREST, Supabase, also has terrific materials online, like this.

After talking with Matt, we have decided that PostgREST does not fit the needs of our project at this stage. We may revisit this technology at a later time if we are expanding our scope.
