[#715] Add healthchecks to two main backend services from Traefik loa…

…d balancer

The commit enhances the Traefik configuration within the
docker-compose.yml.tpl file by adding healthcheck configurations to the
two primary backend services, `metadata-validation` and `backend`. These
healthchecks include defining paths, ports, intervals, and timeouts for
monitoring the health and status of the backend services. By
implementing healthchecks, Traefik can periodically verify the
availability and responsiveness of the backend services through
specified endpoints, contributing to improved load balancing and routing
efficiency. This change directly addresses the user story requirement to
ensure the backend service is correctly defined, reachable, and
functioning optimally in the dev environment for effective testing and
debugging purposes.
