[openmctStaticServer] Fix processLogging telemetry subscription not sent

- The dictionary file was retrieved through an http request, and no route
  function was added through `app.get` on the server side to "evaluate" the
  file (evaluate template literals through `evalTemplateLiteralInJSON`) prior
  sending it. As a result, the template literal defining the "value" was not
  expanded.
