Subject: [PATCH] Tint a selected glass chip so its label stays readable

With glass, a selected chip painted its on-primary label over an
untinted glass plate: light text on light glass. The selected state now
tints the glass with the fill colour (iOS 26), or fills the capsule on
older versions, so the label keeps its contrast.
