* Allow modals in automation

This allows for the opt-in behavior of allowing dialogs while using automation.

When opted in, we also switch over to using custom dialogs & the simple file picker so that the automation can control it.

This was added so that we can do auth flows, which uses dialogs. Now we will be able to complete an auth flow (with the help of the user in the browser) and automate interacting with chat via the development MCP server.

* Instead use custom for smoke tests

* Go back to command but have a context key for automation

* Workaround terminal smoke tests
