fix: native-colour theme icons and palette-correct selector

Draw a resolved icon-theme icon in the colours the theme ships; only
the bundled fallback line art stays tinted to the palette.

The session ComboBox read the system palette for text, background and
the indicator, so its label was near-invisible and the double arrow
came out an unrelated colour. Set buttonText/button/window/dark and
the placeholder colour on the selector and the credential fields.
