Issue: Not displaying execution warnings
If a module is modified between deployments such that it no longer mentions a previously successful future, we generate a warning, but continue with the deployment.

That warning is not showing in the cli UI.
Pull request description: fix: reconciliation warnings (PR B)
Add the reconciliation warnings to the deploying panel.

Fixes #567
