Theme tooltips inside popups

PillButton's attached ToolTip is now a styled instance — uses the
widget's foreground color for text + border and a configurable
tooltipBackground (defaults to a near-black, overridable to
bar.background). No more stock OS chrome inside our popups.

Bluetooth panel passes bar.background/foreground through to its
header pills and replaces the row tooltip with the same themed style.
