Automate "Include organization name in subject of message notification emails" setting

[alya]

Under Settings > Notifications, there is a checkbox setting for whether to "Include organization name in subject of message notification emails". This setting may be difficult to discover when it becomes relevant, however.

For Zulip Cloud users, we can actually make a good guess for the option that will be the best experience for the users. As we say on the help page: "If you belong to multiple Zulip organizations, it can be helpful to have the name of the organization in the subject line of your message notification emails."

We should add an option to automatically select whether the organization name is included in the subject.

Details:

1. Replace the checkbox setting with a dropdown: Automatic [default], Yes, No
2. The Automatic option should include the org name if, and only if, there are multiple Zulip organizations associated with the user's email.
3. Edit the help page accordingly.

We may want to reset the option to "Automatic" for all current users who have not manually changed it.

Hello @zulip/server-settings members, this issue was labeled with the "area: settings (user)" label, so you may want to check it out!

At a database level, this means changing the relevant field from a boolean to an enum and then adjusting the UI.

I'm still working on this issue, just been busy with exams the last few days.

@timabbott and @alya I have now done what I believe are the appropiate changes in the database. I do have a bit of a difficult time figuring out the next step. Are there any changes that needs to be done in the backend?

Before starting, I just want to confirm, since the issue is nearly 1 year old.
There is no change in the plan to handle this issue, right ?

Thanks.

Yep, everything still looks good to me -- thanks!
