Improve permission denied message

[fioddor]

Is your feature request related to a problem? Please describe.

Users without write access to .kibana index are offered the Edit opition and others they are not really entitled to use.

Once they ask to save or edit a panel an 'Application Not Found' error is shown.

This message doesn't provide useful clues.

Describe the solution you'd like

The best solution would be to rethink the user experience.

Describe alternatives you've considered

Improving the message adding a "You might perhaps lack the needed permissions?" should suffice and go a long way already.

Additional context

Hi, what action were you trying to perform when this error surfaced? I agree, this message should be a permission denied message instead of a not found message.

Just an additional note - that loading spinner should not appear on top of the error message.

Should we re-route this to the security plugin @CPTNB? From OpenSearch Dashboards Core perspective it attempted to read the system index and the security plugin intercepted and filtered that component out so from our side of the app we think we showing the right message.

Oh, the security plugin doesn't give us an unauthorized indication? Sounds like we'd need to get a change in both the security plugin and core to (1) know it's an auth issue, and (2) display an auth error.

In the first place, users without write access to .kibana index shouldn't be offered the Edit option or other options they are not entitled to use.
