✨(helm) allow all keys in configMap as env var in backend jobs

Add `envFrom` support to backend jobs and cronjobs
(`backend_job.yml`, `backend_job_createsuperuser.yaml`,
`backend_job_migrate.yaml`, `backend_cronjob_list.yaml`),
mirroring the `envFrom` support already added to the deployments.

This allows injecting all keys from a ConfigMap or Secret as
environment variables via `backend.envFrom` in the Helm values.
