[iOS] Admin Dashboard - Migrate to Own Coordinator/Folder

[JPKribs]

This looks a lot bigger than it is...

Summary

This does the follow tasks:

1. Rename all instances of UserDashboard to AdminDashboard
2. Move all AdminDashboard items into their own folder (No longer inside the SettingsView folder)
3. Create an AdminDashboardCoordinator and move all coordinator AdminDashboard items from the SettingsCoordinator
4. Ensure that all AdminDashboard ViewModels are in the iOS Target Build only
5. Add the following to the AdminDashboardView to better mirror the SettingsView:

        .navigationBarTitleDisplayMode(.inline)
        .navigationBarCloseButton {
            router.dismissCoordinator()
        }

I also added all the AdminDashboard ViewModels to a single folder to clean up the ViewModels folder a little bit. Everything is tested and working as expected. Functionally, the only difference is the AdminDashboard is a Modal instead of a Push.

Thank you for doing this! I only changed it back to a push instead of a modal.

Thank you for doing this! I only changed it back to a push instead of a modal.

My only reason for that was so I could init from here. But, I realized that would be called from a totally different coordinator (HomeCoordinator) so push completely works here!
