This PR implements a set of essential security enhancements for production deployment. These changes address potential risks related to insecure transmission, session hijacking, clickjacking, and MIME sniffing.

🚨 Severity: HIGH (Production Hardening)
💡 Vulnerability: Missing security headers and insecure cookie configurations in production.
🎯 Impact: Without these settings, the site could be vulnerable to Man-in-the-Middle (MitM) attacks, session hijacking, and clickjacking.
🔧 Fix: Added a production-only security configuration block in config/settings.py, gated by the DJANGO_PRODUCTION environment variable.
✅ Verification: Ran uv run python manage.py check --deploy with DJANGO_PRODUCTION=1, which now shows only the SECRET_KEY warning (to be handled via environment variables in Vercel). Existing tests pass.

- Enable SSL redirection, HSTS, and secure cookies when `DJANGO_PRODUCTION=1`
- Configure `SECURE_PROXY_SSL_HEADER` for Vercel deployment
- Set `X_FRAME_OPTIONS` and `SECURE_CONTENT_TYPE_NOSNIFF` for browser-level protection
- Add security journal entries in `.jules/sentinel.md`
