Statically-addressed home servers on hi run no DHCP, so they learned a
resolver only from the v6 RA RDNSS and lost DNS whenever v6 (and thus
the RA) was absent. Factor the fix castle/palace applied inline into a
shared lib.my.c.home.vlanDns helper that points resolved at the VLAN's
VRRP VIPs (always-present static v4, plus v6 when up) and sets the
advertised search domains, then apply it to every statically-addressed
hi client: castle, palace, cellar, sfh and the sfh hass/unifi
containers. Document it under the router client DNS section.

castle took its resolver solely from the IPv6 RA (radvd RDNSS) on
lan-hi, so DNS broke whenever RA was absent. Since castle's own v6 is
RA/SLAAC-derived it has no usable v6 address in that case, so anchor
DNS on the always-present static v4 via the VRRP VIP, with the v6 VIP
as a bonus when v6 is up. Search domains reuse the centralised
lib.my.c.home.searchDomains list.
