[PrintingSelector] Load the pin badge through the themed icon engine

Browse source 
The badge rasterized `theme:icons/pin` with QImageReader, which cannot resolve
the palette token and left the glyph at its first-render colors. Ask QIcon for a
64x64 logical pixmap instead, and re-render the badge when the palette or theme
changes so it stays legible against both card art and the surrounding UI.
