fix: restore AP gateway for DHCP client routing

AP gateway was set to 0.0.0.0 to prevent routing issues, but this
broke DHCP — clients didn't get a default route through the board.
Now set ap_gw = ap_ip so DHCP advertises the board as gateway,
while the STA default route handles outbound internet traffic.
