Self-hosted user UI

[nbradbury]

In this PR, I've combined #21264 (self-hosted user list) and #21270 (self-hosted user detail). This did make for a larger PR, but it should be easier to review than having separate PRs, plus a lot of the code is Jetpack Compose which can be quite verbose.

To test:

• Enable self_hosted_users in debug settings
• Switch to a self-hosted site
• Note that a new "Users" item appears
• Tap on that and verify the list screen with dummy data looks fine
• Tap a user to view the detail screen and verify that looks fine
• If the user has an avatar, tap it and verify the large avatar view looks fine
• Switch to a non-self-hosted site and verify the "Users" item doesn't appear
• View the various Compose previews of the SelfHostedUsersScreen and verify they look fine (note that remote avatar images won't load in the preview)

Caveats:

• This is a UI-only PR - no network requests are made, instead only dummy data is used
• The UI is somewhat different than in this iOS PR but it's closer to the appearance of the existing People feature on Android

Nice! Exciting to see this feature begin to take shape. The testing instructions passed for me using a Samsung Galaxy S20 running Android 13.

I left a few suggestions to consider, but I do not consider them blockers. Let me know what you think.
