time-series: Changed to headless mqtt service for helm deployment (#897)

This PR converts the MQTT broker service from a NodePort to a headless service to enable direct pod communication, reducing time series processing latency. Additionally, the Grafana dashboard is updated to display processing times in seconds instead of milliseconds.
