feat(stack): full overhaul — hardening, ops tooling, monitoring, analytics, chatbot

Security: deep /api/health (DB+MinIO probes, 503 on failure) + /api/live;
rate-limited public forms with honeypots; real client IP behind Traefik
(--proxy-headers); TipTap URL sanitization on write (nh3); non-root
containers + slim .dockerignore; prod MinIO console bound to 127.0.0.1;
HSTS/nosniff on TLS routers; JWT 8h; no default credentials in code.

Reliability: Alembic migrations (create_all baseline); graceful shutdown
(exec uvicorn); hardened backups (checksums, sanity check, freshness gauge,
optional rclone off-site) + restore.sh + hourly db-backup sidecar (ops
profile); stack.sh ops tooling (deploy/logs/health/backup/restore/monitoring);
.gitattributes LF for shell scripts.

Orchestration: json-file log rotation, pinned images, per-service memory
limits, edge/internal networks, Traefik ping/accesslog/metrics + flood
limiter, conditional minio-setup, pgvector db image, one-shot db-init
(umami + aramesh_chatbot databases).

Chatbot: unified from site-chatbot branch (RAG + pgvector, SSE, ChatWidget).

Monitoring: Prometheus/Alertmanager/Loki/Promtail/Grafana + cAdvisor,
node/postgres/blackbox exporters, provisioned dashboards and 10 alert
rules; alerts delivered to Bale (tapi.bale.ai — Telegram-compatible).

Analytics: Umami on shared Postgres, build-time tracker injection, custom
events (contact/newsletter/phone/chat/lang) via frontend/src/analytics.ts.

Hygiene: CSV export for contact messages and subscribers; upload image
optimization (Pillow); CI script + GitHub-compatible workflow; audit.sh;
gen-env.sh for strong credentials.
