Fix django_site relation error by adding Site configuration

- Add configure_site management command to create Django Site object
- Configure site domain as dt.netcoptech.com during startup (like quantum-digital)
- Update both compose files to run configure_site after migrations
- This fixes the 'relation django_site does not exist' error on /accounts/login/

Django Allauth requires a Site object to work properly.
