Description
When adaptivecards-templating is missing, we should either gracefully downgrade the experience (disable templating) or surface an error via the dev console (or error banner). Otherwise, the designer fails in a less-than-obvious way:

While we're at it, we need to make sure that the designer works correctly when GlobalSettings.enableDataBindingSupport = false; and adaptivecards-templating is unavailable.

Research direction
Start in the Designer path that loads adaptivecards-templating and reproduce the failure with the library unavailable. Check the behavior when GlobalSettings.enableDataBindingSupport = false; done means the Designer either disables templating gracefully or reports a clear developer-facing error instead of failing obscurely.
