The failedAuthHandshakes map accumulates entries for every peer/IP that fails the auth handshake. The only existing cleanup was lazy (triggered when that specific peer calls isNodeAllowedToConnect again) or on success. Peers that probe once and disappear leave entries that grow the map forever.

Fix: extend cleanupExpiredTimeouts() — already called on every heartbeat — to also evict entries from failedAuthHandshakes whose expiry window (FAILED_AUTH_HANDSHAKE_EXPIRY_MS = 1 hour) has passed.

Fixes A-759
