Fine, just use separate netblocks for each physical segment. No need
for bridging.

You have the end-addr argument numerically less than the start-addr.
This is supposed to be a RANGE of addresses. Also, you have set each
in a /16 (255.255.0.0 netmask), so those netblocks are overlapping.
You might need to read up a bit on IP networking basics: addresses,
netmasks/CIDR and subnetting. This might work for what you want:
# eth0 being 192.168.4.1/24
interface=eth0
dhcp-range=192.168.4.128,192.168.4.191,255.255.255.0,12h
# wlan0 being 192.168.5.1/24
interface=wlan0
dhcp-range=192.168.5.64,192.168.5.127,255.255.255.0,12h
In that example I use addresses on subnetting boundaries rather than
decimal numbering boundaries. The eth0 range could be described in
CIDR terms as 192.168.4.128/26, and wlan0 range is 192.168.5.64/26.
For NAT purposes, 192.168.4.0/23 covers them both.
