aiosendspin starts its zeroconf on [bind_ip], or on InterfaceChoice.Default
when bind_ip is 0.0.0.0. Default egresses via the pod's main-table default
route (eth0); net1 routes sit in the sbr table. MA therefore never sent
_sendspin._tcp queries onto v30iot and only rediscovered Voice PEs when they
announced on their own, leaving them disconnected for hours after every MA
restart (e.g. 2026-10-26 13:56: 3 of 4 still offline at 15:05).
The reconcile initContainer now writes bind_ip = the live net1 address it
already computes for publish_ip. The address is read from the interface on
every boot, so the Sendspin no-bind-fallback failure (stale literal IP)
cannot recur.
