'Option domain' not changed by "Domain of DHCP clients in DNS" setting

Visiting page /foris/config/main/dns/ (foris) or /reforis/network-settings/dns (reforis)

then changing value in "Domain of DHCP clients in DNS" to: home.arpa

Option 'Enable DHCP clients in DNS' is enabled.

it will change only option local and not option domain in file: /etc/config/dhcp

        option local '/home.arpa/'
        option domain 'lan'

as can be seen in code at: https://gitlab.labs.nic.cz/turris/foris-controller/foris-controller/-/blob/aa868245cdeba85fcad675be7f73646888c7592f/foris_controller_backends/dns/init.py#L272-275

            if dns_from_dhcp_domain:
                backend.set_option(
                    "dhcp", "@dnsmasq[0]", "local", "/%s/" % dns_from_dhcp_domain.strip("/")
                )

The file /etc/resolv.conf will use the value of option domain for search like: search lan

thus nslookup will fail (NXDOMAIN) for compname, but will work for compname.home.arpa

fix: change value option domain as well to use value from "Domain of DHCP clients in DNS" (but not enclosed in / chars as used in local option), so will result in following change:

        option local '/home.arpa/'
        option domain 'home.arpa'

this will make nslookup compname works
