🔧 Fix Django 4.0+ CSRF_TRUSTED_ORIGINS and CI settings

✅ Fixed issues:
- Added proper CSRF_TRUSTED_ORIGINS with schemes (http://, https://)
- Added missing sys import in test settings
- Updated ALLOWED_HOSTS to include 'postgres' container
- Removed duplicate database creation in CI pipeline
- Fixed empty CSRF_TRUSTED_ORIGINS causing Django 4.0.E001 error

🐳 CI/CD improvements:
- Database container properly referenced in settings
- Test environment variables correctly configured
- Eliminated database creation conflicts

Ready for trusted repository CI/CD execution!
