Change the color of Django admin for Stage

[mathildepm]

This would require doing some research into Django Admin, but it would be nice to change the background color of Admin for real Huxley vs stage Huxley. This helps when doing tests with data, and reminding the USG Tech which platform they are working on.

• A Tech who once accidentally deleted assignments from real Huxley that the schools had already finalized (it was resolved but goodness was it a scare)

How are real Huxley and stage Huxley currently differentiated?

From what I can see, there is probably some sort of a local settings config stored in the settings directory on whatever server is running prod.

If that is the case, modifying the local settings config to change prod's Admin colors is probably the best bet for a custom solution. Ex https://github.com/dizballanze/django-admin-env-notice

If you prefer not to touch prod, we can have local settings for dev Huxley but this implies that everyone who uses dev Huxley actually remembers to set up local settings by creating a local.py file.
Also the existing template seems kinda odd... probably worth deleting or updating.

This is probably the winner tho... Out of the Box 3rd party solution: https://github.com/fabiocaccamo/django-admin-interface
