ap: bridge wired LAN port (enx00e04c331140) into br0 with the AP

Browse Source 
Add a wired LAN port on the same 10.42.0.0/24 segment as VanLink WiFi by
bridging both into br0. The gateway IP, dnsmasq, and NAT move off the wlan name
onto br0; hostapd (not networkd) enslaves the wlan via bridge=br0, since a
station-mode wlan can't be bridged until it's in AP mode. NM leaves the wired
port unmanaged so networkd owns it. Failover/Starlink (enxd8ec5eeb3512)
untouched.
