feat(server): wait five minutes before sending email on new album item (#12223)

Album update jobs will now wait five minutes to send. If a new image is added while that job is pending, the old job will be cancelled, and a new one will be enqueued for a minute.

This is to prevent a flood of notifications by dragging in images directly to the album, which adds them to the album one at a time.

Album updates now include a list of users to email, which is generally everybody except the updater. If somebody else updates the album within that minute, both people will get an album update email in a minute, as they both added images and the other should be notified.
