No warning before modifying a model that will break downstream dependencies

Describe the bug

If you make a model, make questions out of it and then modify the model, you don't get a warning if you're going to break questions that will use the model/field that you modify

To Reproduce

1. create a model from the orders table
2. x-ray it, save the x-ray
3. modify the model now, remove the created at field, save
4. see that your saved dashboard from the x-ray broke (and most questions out of it, but you never got any warning

Expected behavior

We should tell the user that it's going to break downstream dependencies (as we track these)
