Description

Communicate errors clearly to the user when any external service requests fail (Edge, OIDC provider etc).

Similar issue we've already closed for 1.6 at some point: #802

@Va1ter Please decide on the component to use in the client app.

This is an issue with a instance or the customer has internet connection issues.

@kchudy we have a "general view" for the errors in the client app https://www.figma.com/design/10nZVPFPMUocY4aZqpFjD1/Defguard-Desktop-App-2.0?node-id=322-9089&t=Y7xPmnI5GN7mGoDW-11 - we need just adjust e the content for specific scenario and we are good to go imho
