fix: cream background on every style, warm highlight on cursor row

Every Lip Gloss style now has Background(ScreenBg) so ANSI sequences
carry the cream color inherently. Previously only PadLine added bg
to padding spaces, but inner escape codes reset the background.

All spacing between styled segments uses bg()/wbg() helpers.
Cursor row elements use Background(Warm) for highlight.
