Tweak messages if synthetic data

[mccalluc]

• Fix "Select columns to calculate statistics on": Should be different for synth data #681
• Towards Split panel files into smaller components #636 : I realized that these can't be pulled out completely because the selectize lists won't update in dynamic ui.

For reviewer:

• Do the messages look good? We don't really have "grouping" for synthetic data, but changing that based on the product type would get really annoying, and this might be fine with users.
• Any other places where the display should be conditional?

@mccalluc if 'grouping' isn't appropriate for synthetic data, can the input in the Grouping card be disabled, when the user chooses synthetic data?

It's still useful for generating synthetic data, because the string-valued columns can't be selected for analysis... Maybe that's what needs to be tackled first? But I don't want to make the code much more complicated for something that feels like a pretty minor UI feature.

Not sure about the best course here: I'll give it more thought, but if you have suggestions, that's great, too.

I'm not sure I understand your original comment - 'We don't really have "grouping" for synthetic data, but changing that based on the product type would get really annoying, and this might be fine with users.'
