Auto-Sync tile: light for the WHOLE pipeline, including scheduled auto-sync

The tile's liveness was wired to sync:progress / discovery:progress — both
ROOM-scoped (only clients watching a specific playlist receive them), so the
dashboard tile would basically never light. And the scheduled auto-sync runs
as an automation, reporting on automation:progress — the wrong tile.

The 1s sync emitter now also sends an UNSCOPED sync:active heartbeat while any
playlist work is running anywhere: manual per-playlist syncs (sync_states),
the UI-triggered mirrored pipeline (playlist_pipeline_progress_states), and
scheduled auto-sync pipelines (running automations whose action_type is
playlist_pipeline / sync_playlist / refresh_mirrored). Emitted only while
active; the tile's 6s freshness decay handles the off. The dashboard listens
for the heartbeat alongside the (kept) room-scoped signals.
