When both instances have autoAcceptPeering off, the approval flow
ping-ponged indefinitely. Admin A approves → handshakes to B → B
queues (202) → A's peer becomes awaiting_approval. Admin B approves →
handshakes to A → but A's gate only matched 'pending', not
'awaiting_approval', so it re-queued instead of accepting.
Now the gate matches both 'pending' and 'awaiting_approval'. When the
second admin approves and handshakes back, the first instance recognizes
its admin already approved and accepts — completing the peering.
