Cobra 3cdccbf47d Fix WiFi conflict and SSH accessibility on fresh flash
- Remove wpa_supplicant@wlan0.service enablement: Netplan spawns its own
  wpa_supplicant instance, enabling the @wlan0 unit creates a second one
  that fights for the socket, causing WiFi instability and SSH drops
- Write /etc/nftables.conf to card at flash time: Armbian bookworm default
  nftables policy drops all input; SSH was unreachable despite sshd running.
  Ruleset allows established, loopback, ICMP, and TCP/22 only

Fixes DevTrack #317 and #295
