translation.jadpo_missing: A supported locale lacks wording for Jadpo's own messages

A supported locale lacks wording for Jadpo's own messages.

Area 10, Configuration and time; not declinable; the next step is usually the agent's.

Jadpo ships its own wording in en_gb and en_us. An application that supports another locale words the messages of the features it has on itself, in the root translations/<locale>.jadpo under jadpo: { }, so the users and client apps using it are not shown English; here the notes app has a route and French has no root file.

example

use notes/types { NoteRequest, NoteShown }use notes/actions { echo_note }routes Notes {    prefix: /notes    POST / {        authentication: RouteAuthentication.none        input: NoteRequest        output: NoteShown        run: echo_note(input)    }}
