feat: (hud) Effects Modern mode draws a per-effect duration bar

The Modern potion widget showed name and remaining time as text only.
It now renders an opt-in progress bar under each effect (toggle
DurationBar), scaled against the highest duration seen for that potion
so the bar depletes as the effect runs out.
