HostServ: forbidden-vhost patterns + auto-vhost template

Browse source 
FORBID <regex> / FORBIDLIST / FORBIDDEL let operators block impersonating
user requests (e.g. (?i)(admin|staff)); REQUEST refuses a matching host.
Matching reuses the linear-time RegexSet, so untrusted patterns are safe.

TEMPLATE <$account...> sets a network auto-vhost pattern; DEFAULT gives a
user $account.users.example with their sanitised account name. HostServ's
node config (offers/forbidden/template) is consolidated into one HostConfig
threaded through the log replay.
