It may be that enabling DHCP without NET_MGMT shouldn't be allowed

Yes, that is the case. After looking the code, the DHCP needs to know about the network interface status in order to trigger a renew when the network interface comes back up. It looks like we are missing proper selects for net mgmt config option in subsys/net/ip/Kconfig.ipv4 for DHCPv4.

net: dhcpv4: The client needs info about network interfaces

DHCPv4 client code needs to know information when network
interfaces are going down and up. So make sure that network
management config options are enabled in that case.

Fixes zephyrproject-rtos#33137
