Add api/status.php — reads all scheduled jobs' stat files and returns a
{id: status} map. The scheduler page polls it every 3s and lights up the
dot on any job whose stat shows status=running, clearing it when done.
Replace single vvRunningId with vvRunningSet (Set) so multiple jobs can
show as running simultaneously. vvSetDot/vvClearDot handle per-job dots
and the header dot for the active job. Remove stale-count detection from
vvFetchRight — status poll is now the single source of truth.
