refactor: Update Dockerfile.tpl to expose port 8547 instead of port 80

This commit modifies the Dockerfile.tpl file to update the EXPOSE directive. The port number is changed from 80 to 8547 to align with the port used by the Llama application. This change ensures that the Llama application is accessible from outside the container on the correct port.
