The fanoutOutboundSubscribers helper is called from onPeerActivated,
the single point all peer activations flow through (queue approval,
/peer/initiate, autoAccept=1 remote, mutual-approval token verification).
Subscribers see kind='approved' notification, parent + subscriber rows
cascade-delete. Critical: cleanup triggers on status->active, not on
the local approve action — when the remote also gates, the peer goes
to awaiting_approval first and subscribers must remain queued.
