Change unlisted icon to moon

[rrgeorge]

Is your feature request related to a problem? Please describe.
Mastodon is changing the unlisted icon to a moon, so I guess it should be a moon now

Describe the solution you'd like
Change the icon to a moon

Describe alternatives you've considered
If it's undesirable to wholesale change the unlisted icon to a moon, maybe just when connecting to a mastodon server?

Additional context
See: mastodon/mastodon#28119

But I hate "🌙 quiet public" so much! Also, the moon on iOS means "do not disturb", generally. Kinda weird to re-use it for that. Maybe I'll put it behind a switch.

I do like the idea of auto-configuring some UI defaults based on the server type, though, especially if implementations start to diverge in what vis levels they offer.

At least I'm only suggesting the icon 😅
But I was thinking it might be a good candidate for another switch ala Post/Toot

I think this is ultimately going to become a necessity for better UX
