User & Group Manager: Improve Deny Config Write Handling. Fixes #9259
Denies all changes if a user has the Deny Config Write privilege. Previously it only denied the config write but some OS operations were performed.
Sets an input error so the user is notified that their attempt failed.
Hides the add and delete buttons so read only users don't see the option to perform those actions (but are still denied if they submit the form through other means)
