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

[HeyBanditoz]

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.

@mertalev @jrasm91 anything you guys would like to address in this PR?

We talked about different approaches for notifications, but came to the conclusion that this approach is fine for now until we have a more detailed plan on how notifications should be scheduled.

@mertalev @alextran1502 I've resolved conflicts, this should be ready for review now

Just a thought: i'd love to see this either configurable (which would be a lot more work I assume), or have 60 seconds bumped up to something way higher, like 15 minutes or something. Like, why not?

Let's get this pull request through first. I just went on vacation with some friends and they always complain when someone uploads one or more pictures. I had to temporarily completely deactivate the email notification function until further notice so that your inbox wouldn't be flooded.

Yeah I picked 60 seconds since it takes a quarter of that time to upload an image one-by-one to my VPS running Immich.

If I recall correctly. a workaround to prevent the notification flood is to upload all the images to your user, then navigate to the album and bulk add them there (plus at top right on web) so they aren't added one-by-one.

I think 60s is a little too short considering videos and slower connections. 300s would be nicer imo
