nftables.conf hardcoded the R5C network, van-br0-setup.service the R5C
interfaces and several configs wlan0/eth0. All now come from the host
config; the onboard LAN port is skipped when ONBOARD_LAN_IFACE is empty.

systemd-networkd Bridge= directive wasn't reliably adding interfaces to br0
on Armbian. Created persistent systemd service to ensure enP2p33s0 and wlp1s0
are added to the bridge after boot, maintaining 10.42.1.0/24 network.
This ensures the gateway bridge stays configured even after R5C reboots.
