daniel-c-harvey be1a55fd37 feat(stats): flip home Plays card live (Phase 16.5)
Add TotalPlays + UniqueListeners to HomeStatsDto, composed at
StatsController from IEventService (no migration). Card reads via
existing persistent-state-bridged round-trip.

@* Plays — live site-wide play total in the odometer (the "90s visitor counter" aesthetic is the
intended treatment). Secondary line is unique anonymous listeners (Phase 16 D7). Both read from
the same HomeStatsDto round-trip the other two cards use — no extra fetch. Reads zero until the
play-telemetry migration is applied. *@
