feat: замена Kafka → shared-SQS в IoT pipeline

- mqtt-bridge: kafka.Writer → SQS SendMessage (AWS SDK Go v2)
- kafka-consumer → sqs-consumer: polling loop с ReceiveMessage/DeleteMessage
- admin stats: Kafka lag → SQS GetQueueAttributes
- Удалён kafka-consumer, добавлен sqs-consumer
- go.mod: убран segmentio/kafka-go, добавлен aws-sdk-go-v2
- Dockerfile, Makefile: kafka-consumer → sqs-consumer
- .gitignore: исправлен чтобы не игнорировать cmd/ директории
- deployments: новый iot-sqs-consumer.yaml, обновлён mqtt-bridge
- doc/decisions: задокументировано решение
