onOutbounds wrote the raw WebSocket payload straight into the
outboundsTraffic cache, unlike the sibling onNodes/onInbounds handlers which
first check Array.isArray. A malformed non-array push (for example an object)
would land in the cache with staleTime Infinity; consumers that call
.find()/.map() on the outbounds list would then throw and crash the Outbounds
tab. Add the same Array.isArray guard so a bad push is ignored.
