feat: Core models implementation - Phase 1 complete

Settings Configuration:
- Split settings into base.py, local.py, production.py
- Configured all 60+ installed packages
- Set up PostgreSQL, Redis, Celery, Channels
- Configured caching, sessions, logging
- Added security settings for production

Core Models (apps/core/models.py):
- BaseModel: UUID primary key + timestamps + lifecycle hooks
- VersionedModel: Automatic version tracking with DirtyFieldsMixin
- Country, Subdivision, Locality: Location reference data
- DatePrecisionMixin: Track date precision (year/month/day)
- SoftDeleteMixin: Soft-delete functionality
- ActiveManager & AllObjectsManager: Query managers

User Models (apps/users/models.py):
- Custom User model with UUID, email-based auth
- OAuth support (Google, Discord)
- MFA support fields
- Ban/unban functionality
- UserRole: Role-based permissions (user/moderator/admin)
- UserProfile: Extended user info and preferences

App Structure:
- Created 7 Django apps with proper configs
- Set up migrations for core and users apps
- All migrations applied successfully to SQLite

Testing:
- Django check passes with only 1 warning (static dir)
- Database migrations successful
- Ready for entity models (Park, Ride, Company)

Next: Implement entity models for parks, rides, companies
