feat(k8s): add RabbitMQ configurations and update secrets

Add a new extract for RabbitMQ in the secrets and include
AMQP_URL in local secrets. Update the merge policy and
engine version in the deployment template. Remove unused
RabbitMQ secret reference from the deployment. These changes
improve configuration management and ensure consistency
between environments.
