fix(installer): use a stable per-network wifi MAC

A fresh MAC per connection hides the machine from itself as well as from the venue, so every reconnect at a hotel or airport looks like a new device and the portal login starts over. Stable derives a different address per network, so nothing is given up across networks and the reconnect friction goes away. Ethernet already used stable.
