Show the CORS settings in the UI when enable_general_settings_admin=0 (#13660)

* Show the CORS settings in the UI when enable_general_settings_admin=0

The INI setting description does not mean to include CORS:
```ini

; By setting this option to 0, the following settings will be hidden and disabled from being set in the UI:
; - "Archiving Settings"
; - "Update settings"
; - "Email server settings"
enable_general_settings_admin = 1
```

* improve the meaning of enable_general_settings_admin = 1

* Do not allow to configure trusted hostnames if general settings are disabled
