### What should this feature add?

Currently we have one "global" error boundary, catching exceptions that bubble up to the root of the application.

We should implement much more granular error boundaries across the application.

This could be implemented in parts:
- enhance the error boundary fallback component to be more descriptive and useful
- scrollable area to display the full error?
- probably should have a "refresh" button in addition to "reset", as often all that's needed is to refresh the page
- make it configurable using `AppConfig` / `configSlice` so that eg commercial can provide their own components or URLs
- utilize it in other areas - like one for canvas, one for nodes, one for gallery, etc
