Fix related name conflicts and allow sqlite migrations

[2-Coatl]

Summary

• rename related_name fields to avoid user model conflicts across configuration and permissions modules and register the granular permission model
• add bcrypt and scikit-learn to the base requirements and enforce unique related_name expectations with new unit coverage
• guard SQL-heavy permission migrations and merge dashboard branches so migrations run cleanly on SQLite in development

Testing

• python manage.py migrate --noinput
• python manage.py check
• pytest tests/unit/test_related_names_conflicts.py
