Upgrade Django to 5.0 + upgrade python to 3.12.1 (if 3.12 is possible)

[JasonLovesDoggo]

Django

essentially look at the changelog for 4.2 and 5.0 and see what we use (also actually upgrade and test to see what breaks...)

• [x] django 5.0 (thank you sean)
• [x] python 3.12

Python

Simply upgrade your local version see what's broken
