fix: Uncheck group limit in admin settings

[elzody]

• Resolves: #3506
• Target version: main

Summary

Previously, trying to uncheck the checkbox would simply re-enable it automatically. This PR fixes this issue. Also adds an inputLabel prop to the NcSelect so it doesn't error anymore (and accessibility reasons :D)

Thanks for looking into this. We used to hide the select if the box was unchecked. Maybe we can bring back this behaviour as well?
