fix(tinode): auto-recover from cluster-failover topic proxy teardown

Browse Source 
Native Cluster failover tears down a topic's server-side proxy session
on the surviving nodes without notifying the client -- the SDK's local
_attached flag is never reset on this path, so isSubscribed()/
ensureTopicAttached() keep reading a stale true and can't catch it in
advance. The server replies 409 "must attach first" to the {pub}
itself; publishWithReattach() catches exactly that, forces a fresh
subscribe(), and retries the same msg object once (safe: publishDraft's
own _noForwarding guard prevents a duplicate local echo, and the
unchanged x-im-client-mid still dedupes server-side). Wired into all 9
publishDraft call sites (send.ts, attachments.ts, calls.ts).

Confirmed live on an independent native-Cluster verification
deployment: killing the leader pod mid-conversation previously caused
every send to fail until a manual resubscribe; with this fix, 36/36
probes across the same failover succeeded with no manual intervention.
