Update page title and authMessage string handling

Updated the title of the page in `CascadeAuthState.razor` from "Cascade Auth State" to "Authentication State and Authorization Check". The `authMessage` string now uses the user's name from the "name" claim instead of the `Identity.Name` property. Also, the wording of the `authMessage` string has been modified for both Admin and non-Admin roles, with a specific change in the phrase for non-Admin users.
