deploy: EMQX, iot-operator, managed Postgres, Docker Hub image

- Добавлен EMQX deployment + WS ingress (адаптирован из sless)
- Добавлен iot-operator deployment с RBAC (ServiceAccount, ClusterRole)
- Postgres: заменён self-hosted на managed (dc5db45d namespace)
- Image: naeel/iot-operator:v0.2.0 (Docker Hub)
- Убран imagePullSecrets (Docker Hub публичный)

+# EMQX MQTT-брокер для IoT-сервиса (namespace: sless).
+#
+# Архитектура:
+#   IoT Device → MQTT CONNECT → EMQX (HTTP auth → iot-operator:9090/internal/mqtt/auth)
+#   EMQX → MQTT PUBLISH → iot-mqtt-bridge (paho subscriber) → shared-SQS queue iot-telemetry
+#   SQS → iot-sqs-consumer → Postgres
+#
+# EMQX 5.x конфиг через emqx.conf (HOCON формат), монтируется как ConfigMap volume.
+#
+# Порты:
+#   1883 — MQTT (plaintext)
+#   8083 — MQTT over WebSocket
+#   18083 — EMQX Dashboard (admin/public по умолчанию — менять в prod!)
+#
+# Применение: kubectl apply -f deployments/k8s/emqx.yaml
