Subscribes to devices/+/telemetry, validates payloads, buffers writes into ClickHouse (flush on size or interval), and emits a per-reading event on RabbitMQ for rule-engine-service to consume later. Adds the initial Postgres and ClickHouse schema migrations, a Dockerfile, and wires the service into docker-compose. Verified end-to-end via docker compose + mosquitto_pub: row lands in ClickHouse and the event reaches the telemetry.new_reading queue. Co-Authored-By: Claude Sonnet 5 <noreply@anthropic.com>
