feat(orgviewer med): [#48311] template environment variables directly

Previously, environment variables were templated into a ConfigMap which
was referenced through an `envFrom` in the deployment. Unfortunately,
Kubernetes does not restart deployments on changes to their referenced
ConfigMaps[1], so this indirection means that deployments have to be
restarted manually every time a change is made - something that is very
easy to forget in an otherwise GitOpsy workflow.
