Automate manual release system tests

### User Story

As a developer, I want the minimum manual steps in order to release Sleeper, so that I can spend more of my time on development.

### Description / Background

We'd like to automate away the steps in the release process where we manually deploy Sleeper and run some scripts against it.

### Technical Notes / Implementation Details

See sub-issues.

Begin by reviewing the release process and the sub-issues referenced in the description. No files, tests, or specific entry points are named, so use those sub-issues to identify the manual deployment and script-running steps to automate. Done means the relevant release system tests run without those manual steps.
