FEAT: Add periodic cleanup command

Currently performs two functions:
1. Inactivates users that have not logged in for at least one year. Closes #478 (Need to circle back round to full deletion SoonTM)
2. Ensures the supervisor database flag is set correctly for each user

This is run automatically by the Heroku Scheduler addon at midnight daily.
