security(iot): MQTT ACL isolation via EMQX HTTP authorization
Each IoT device can only pub/sub to its own topics: {namespace}/{deviceId}/#
Any attempt to access foreign topics → EMQX denies and disconnects.
Changes:
- internal/api/handler: add MQTTAcl handler (POST /internal/mqtt/acl)
- internal/api/router: register /internal/mqtt/acl route
- deployments/k8s/emqx.yaml: add HTTP authorization backend, no_match=deny
- Operator v0.1.52 deployed
Tested: own topic ALLOWED, foreign topic → authorization_permission_denied + disconnect

feat(iot): Этапы 2-7 — MQTT auth, IoT API, EMQX, mqtt-bridge, E2E demo
Этап 2+4: internal/api/handler/iot_device_handler.go
- MQTTAuth: POST /internal/mqtt/auth (без JWT, для EMQX)
- CreateIoTDevice, ListIoTDevices, GetIoTDevice (c password), DeleteIoTDevice, UpdateIoTDevice
- crypto/subtle.ConstantTimeCompare против timing attacks
Этап 4: internal/api/router.go
- /v1/namespaces/{ns}/iot/devices CRUD
- /internal/mqtt/auth (без JWT middleware)
Этап 3: deployments/k8s/emqx.yaml
- EMQX 5.5.1, emqx.conf (HOCON) с HTTP auth backend
- Сервис exposure: 1883 (MQTT), 8083 (WS), 18083 (Dashboard)
Этап 3: iot/cmd/mqtt-bridge/main.go
- paho.mqtt.golang: подписка на +/telemetry/+
- amqp091-go: publish в iot.{namespace}.telemetry
- deployments/k8s/iot-mqtt-bridge.yaml
Этап 7: examples/IOT/ — E2E demo (main.tf, handler.py, README.md)
go.mod: добавлен github.com/eclipse/paho.mqtt.golang v1.5.1
go build ./... — ошибок нет
