list ui selector layout fixes

* The `DisplaySelector` wasn't getting the correct flex layout.
  Before this was done by a manual style on a `Paper` element. That
  broke when adding the inner `<CardContent>` to because that's the
  container that needs the `display: "flex"`. But really, it's clearer
  to do this with `<FormGroup>` anyway, so do that.

* Switch from `<Card><CardContent>` to `<Paper sx={{ padding: ... }}>`.
  The card content has extra padding (16 px in general, 24 at the bottom
  of the last element to fit with an action). I'm not quite sure the
  best way to remove it, and the simpler `<Paper>` seems fine for this
  use anyway.
