Tech debt: Fix emails in dev

[BCerki]

As a developer
I want to set up a fully functional smtp endpoint for transactional emails
so that I don't have to use a gmail workaround.

Tasks

• set up endpoint
• remove code related to the gmail workaround
• remove requirement to provide gmail environment variables in order to start the server

Additional notes:

in development, the site uses gmail to test transactional emails in development

Highly recommend using Mailhog in ci/dev/test to create a fully functional smtp endpoint. Here's a good helm chart for Mailhog.
