Check naming and structure of namespaces

There is possibly form code in db (clj), service (clj), api (clj), application (cljs), editor (cljs) and common (cljc). Is this the best structure or what is and how to do the naming. Perhaps make an ADR.

Review the current db, service, api, application, editor, and common namespaces across Clojure, ClojureScript, and shared code. Clarify the desired naming and structure with the project maintainers, then document the agreed architecture in an ADR; done means the namespace organization and naming rules are explicitly recorded.
