Default: fix highlighted ItemDelegate colors

- Make ItemDelegate respect highlightedText
- Change ItemDelegate's highlightedText palette role from white to
  almost black (i.e inversion of "light" which is 0xFF090909),
  so that text shows up against a highlighted background.

This also allows easily switching ComboBox to a dark style via palette
customization.
