feat: collectstatic and whitenoise

[sanchegm]

• install whitenoise to serve static files. Used this documentation: https://whitenoise.readthedocs.io/en/latest/django.html
• ran collectstatic to collect and serve static files to whitenoise. Used this documentation: https://docs.djangoproject.com/en/5.1/howto/static-files/deployment/ and https://docs.djangoproject.com/en/5.1/howto/static-files/
• pin whitenoise version

This is so we can serve these static files in production.

I believe you are right that the static files do not need to be in version control. From the docs, I believe during deployment the collectstatic management command will need to be run - which we can put in a playbook.
