fix(inbox): a Takeout import's notice opens the user's own import

The import's notice reaches a user who may not see the Scheduler, an
admin page, yet its link opened it. It now opens Settings › Account,
where the import's status is; any other run still opens the Scheduler.
The job id is held to the server's by the backend-ids contract. The
notice's Hungarian names the list as the app does elsewhere.
