* A send whose routing ACK/NAK never reaches the app (typically because it was disconnected when the radio's

* response arrived) would stay ENROUTE — "Sending…" — forever. Stamp it as a retryable timeout instead; a late ACK

* still upgrades it via handleAckNak.

*

* One timer per packet: re-arming supersedes the pending one, so repeated reconnects cannot pile up timers for the

* same send. Timers deliberately survive a disconnect — the ack genuinely never arrived, and the resulting state is

* retryable — so a user who never reconnects still sees the send resolve.
