Scriptically change theme

[qay21]

We are using 3 SnipeIT servers for differents needs :

• -dev, which is using latest Docker image, allowing us to contribute to translations, test new scripts and integrations and try different management guidelines
• -preprod, which is in many ways equal to -prod, and is mainly started and used during version changes
• -prod, which is obviously the main server

We recently had a few problem with team members updating assets on the wrong server. I would like to set a clear visual identity to non-prod servers in order to avoid such a problem in the future. The theming function is great for that : just set the general theme to Red and done.

However, we tend to refresh -preprod and -dev databases by simply dumping the latest -prod DB backup, and such a backup also include SnipeIT's config options. Consequently, the theme is overriden and back to the usual Blue, which can lead to further issues again.

Is there a way to change the theme other than manually using the admin web interface ? I can't find any env variable that could be used in such a way.
