dnsmasq's SIGHUP re-reads /etc/ethers and any --dhcp-hostsfile= paths,
but NOT dhcp-host= lines from the main conf. Reload() was faithfully
rewriting dnsmasq.conf with the new MAC, sending SIGHUP, and then
dnsmasq kept serving its startup view — so a freshly-registered host
still showed up as "proxy-ignored, tags: eth0" with no "known" tag.
Split the allowlist into ${RuntimeDir}/dhcp-hosts, referenced from the
main conf via dhcp-hostsfile=. writeConf() is static-ish now; Reload
just rewrites the hosts file and SIGHUPs.
