Send the error-notification alert email, either to the store's configured response-posting error recipients (email_to=admin) or to a custom address (email_to=other).

Auth: Partner — authentication, under the partner prefix. The request validation validates notification_id exists; no partner-tree / company scoping on which notification is emailed. The controller 400s if the notification is missing or has empty content (No notification is available), if the linked store is missing (Location does not exist.), or if no recipient resolves (User does not exist.). For admin, recipients come; for other, the email field is used. Mail sent.

Rate limit: No rate limit.
