🚀 Production-ready: Auth enforcement + Observability + Policy

- Atomic генерація всіх секретів (generate-all-secrets.sh)
- Auth enforcement перевірка (enforce-auth.sh)
- Оновлений full flow test (must-pass)
- Prometheus alerting rules для Memory Module
- Matrix alerts bridge (алерти в ops room)
- Policy engine документація для пам'яті

Готово до production deployment!
