Update text preview UI to mocks

Still more details to refine, but structurally this is closer.

- Merge text preview, title and icon into one space.
- Shaded background instead of border (using a themed color, though probably
  not the right one yet, waiting on UX)
- Less padding around text preview area.
- Give title 1 line, text preview 3.
- No border around icon image.
- Move actions to the bottom of the preview.
