Add setting to disable new user registration

[justinmayer]

Describe the feature

As an admin user, I would like to use the Maybe settings panel to disable new user registrations. This could be located under:

Settings > General > Self-Hosting > General Settings > Registration

Ideally, the setting would be a radio button with three options:

• Open registration
• Invitation code required
• Registration closed

Why is this feature important?

Folks who are self-hosting create an account for themselves and perhaps also for family members, after which they may not want random people on the Internet to be able to create accounts on their personal/family instance. Adding a toggle to enable/disable new user registrations would allow for greater control over who can create user accounts on personal/family instances.

Additional context, screenshots, and relevant links

While I am aware of the REQUIRE_INVITE_CODE environment variable, I am not aware of any way to (1) do this via the web interface or (2) disable new user registrations entirely.

@justinmayer agreed, this would be a good self hosting settings feature.

Great! To be clear, I think having the option for open registrations will have plenty of value for some instances, so it would nice to retain that ability. Allowing admins to flexibly toggle between the three states (open, invitation-only, closed) via the web-based settings would be really helpful.

Noted! Just updated the title to be a bit more clear on that.
