fix: correct settings module references and code quality issues

- Fix asgi.py and wsgi.py to point to config.settings.development
- Move timedelta import to top of base.py (PEP 8)
- Add STATIC_ROOT to base.py
- Add Redis OPTIONS with timeout config
- Add dev-only comments for ALLOWED_HOSTS and CORS_ALLOW_ALL_ORIGINS
