Expose MQTT port in Docker Compose file

- Updated `compose/compose.yml` to expose port 1883 for the MQTT service.

By exposing port 1883, the service is accessible externally, enabling MQTT
clients to communicate efficiently with the broker. This change enhances
the configurability and usability of the MQTT setup. 🚀
