Add Guard.IsAdminAuthorized, a fail-closed variant of IsWhiteListed, and use it to gate destructive volume admin RPCs. IsWhiteListed keeps its allow-all-when-empty semantics for HTTP compatibility. For TCP peers with an empty whitelist, off-host callers are rejected but loopback (127.0.0.0/8, ::1) is still trusted. A volume server commonly cohabits with the master/filer on a single host and in integration-test clusters; the loopback exception keeps cluster-internal admin traffic working without -whiteList while still locking out off-host attackers. Non-TCP peers (in-process / bufconn / unix-socket) bypass the host check entirely. When `weed server` runs master+volume+filer in a single process the master dials the volume server in-process and the peer address surfaces as "@", which has no parseable IP. Such a caller shares our OS process and cannot be spoofed by a remote attacker, so we treat it as trusted by construction. The gate also tolerates a nil guard (developmental / embedded path) and only enforces once a guard is wired up. UpdateWhiteList skips entries whose CIDR fails to parse so the IP-iteration path can no longer hit a nil *net.IPNet.
