[iOS] Admin Dashboard - Users Management (Passwords)

[JPKribs]

I wanted to try and make this one a smaller one but it's still coming in at like 800 lines. Luckily, the majority of this work is the ViewModel, Observer, and I almost 100% copy/pasted the ResetUserPasswordView so that one should be familiar with my only addition being a Reset Password button.

This creates a view with all of the users on the Jellyfin Server. It says their name, shows their icon, and has the last time they were seen. This is ordered alphabetically.

Selecting a user takes you to a UserDetailsView. This view WILL contain more items:

1. Profile
2. Permissions (Done, but this is a bigger PR so I wanted to split it up)
3. Access
4. Parental Controls
5. Devices (This is honestly a single line of code once [iOS] Admin Dashboard - Device Management #1277 is merged)

Currently, only the PasswordView is done. This is a direct steal of ResetUserPasswordView but uses my observer's actions instead. This Observer is Eventful so I am capturing a success/failure message depending on the response. The reset password is the only addition to ResetUserPasswordView.

Localizations are missing from this PR. Primarily because, if I localize everything then #1277 gets merged, I have to do a whole thing to update it to this branch. Instead, I am just going to localize everything either once #1277 is done OR, if this branch does in first, I have a branch where I have the User Permissions almost done that I can add the localizations to.

Views

It's out of order... But UsersView | Password | UserDetailsView

Putting on hold for a sec while waiting on #1277

Closing in favor of: #1287.

Passwords will come in their own PR since I'm trying to avoid creating weird bulk PRs and keep things single-focused.
