Scheduled-result notifications: first lines, Open / Run again / Pause; a click opens

A run's own notification (run.notification, server dev) gives the body (the
result's first lines) and the actions with labels in the person's language;
they become the notification's action type. Every notification is
remembered by id (watch::Notes) so a click opens the chat or the task, and
Run again / Pause post /schedules/{id}/run|pause without the window. An
older server's run is said as before. Fixtures re-pinned at server dev
e0c2332, schedule.json added.
