Widgets: add shared WidgetTheme + BarGrid (foundation)

Groundwork for the slate-background / brand-orange widget re-theme and the
new bar-style event countdown:
- WidgetTheme (dark slate background, brand orange accent, text tones).
- BarGrid: vertical-bar (comb) progress view.

Re-theming the existing widgets and adding the bars widget follows.
