feat: power play indicator with live countdown clock

Shows a red pill below the team rows when a PP is active, displaying
the team on the power play and a ticking countdown. PP clock always
resyncs from the API (no local anchoring) since 2-minute penalties
are short enough that accuracy matters throughout. Removed the old
inline PP text from team rows.
