Thanks for assigning this issue to me. I'm starting to work on it and will keep this PR's description up to date as I form a plan and make progress.

Original issue description:

In the PullDialog when we have an error pulling, let's show the error callout we also show on the start screen that lets them understand what was going on and what's the issue.

Fixes #3383.

I've implemented the error handling for the PullDialog as requested. When a pull operation fails, the dialog now shows an error callout similar to the one on the start screen, providing clear feedback about what went wrong. The implementation handles various error scenarios including provider failures, network issues, and empty responses. Changes include error state support, comprehensive test coverage, and proper translations. Commit: 8b620f9
