feat(monitoring): add BE microservice health monitoring with dedup and readable crash alerts

Adds two-layer BE-* microservice monitoring: an aggregate Stack Services replica check across the iklimco and monitoring Swarm stacks (checks/swarm_services.py), and per-service actuator/DNS health checks driven by a new microservice_monitors section in monitors.yml (checks/actuator.py). BE-* services are excluded from the Stack Services aggregate so a single service incident produces exactly one Slack alert instead of two.

Fixes found during QA of the initial implementation: RabbitMQ host derivation generated nonexistent numbered DNS names instead of using the real single-service topology, RabbitMQ and Patroni cluster checks did not push down status on node/member shortfall, and the etcd cluster check still used a hardcoded node list and quorum threshold instead of deriving them from CLUSTER_SIZE_ETCD.

Also hardens Docker event crash alerting: excludes ephemeral Gitea Actions runner containers from crash notifications, skips alerts for containers Swarm intentionally stopped (rolling update/scale-down, detected via task DesiredState) instead of alerting on every deploy, and adds human-readable exit code descriptions to the Slack message.

Uptime Kuma monitor names are now prefixed with "iklim [env]" since test and prod share one Kuma instance and unprefixed names collided. setup_uptime_kuma.py gained an ensure_push_monitor helper and a microservice push-monitor creation pass. Removed state.py and the unused restart_threshold config field (dead code, no longer referenced anywhere).

+**Mikroservis Ekleme:** `microservice_monitors` bölümü, BE servislerinin Uptime Kuma'ya (actuator ve swarm replica bazında) eklenmesini otomatikleştirir. Yeni bir BE servisi eklendiğinde kod değişikliği gerekmez; sadece bu bölüme servis tanımı ve opsiyonel `replicas.<env>` beklentisi yazılıp setup script çalıştırılır. `replicas.<env>`, ortam bazlı beklenen replica sayısıdır; Docker "desired" değerinden bağımsız çalışır (yanlış scale-down veya deploy edilmeme durumlarını alarm olarak yakalar). Servisin replica değerini kalıcı olarak değiştiriyorsanız, `monitors.yml` dosyasını da güncelleyip imajı rebuild etmelisiniz (çünkü bu dosya imaja gömülüdür).
