Feature: reset & re-seed Demo DB daily

[evereq]

We need to have a tiny script that runs on a daily schedule to recreate DB and run Seed again. It's best to move Seed logic to server. However, at the moment some of the seed functionality is on the client-side and we can use https://github.com/microsoft/playwright to make tiny automation script which will login into the demo site and manually make a "click" on Seed button.
