Custom Email text for ODK Central Emails

1. What is the general goal of the feature?

To customise the text of emails generated from ODK Central e.g. new users, changed password etc. This would be to include company/organisation signatures or terms and conditions to emails.

2. What are some example use cases for this feature?

Customised email text is available in REDCap, and my organisation will require that emails sent to external recipients include the default mail signature as policy.

3. What can you contribute to making this feature a reality?

I can see that the existing email text is configured in /central/server/lib/outbound/mail.js. I guess we could edit this file and restart the service, but was hoping there might be a better way than editing the source file, perhaps something in the .env file.
