feat: distinguish UPSTREAM vs FORWARD in logs and stats

Browse Source 
Queries matching a [[forwarding]] suffix rule now log as FORWARD;
queries resolved via the default [upstream] pool log as UPSTREAM.
Previously both paths shared the FORWARD label, making it impossible
to tell from logs whether a rule matched.

Adds QueryPath::Upstream, a queries.upstream stats counter exposed
via /stats, plus a matching dashboard filter, bar, and path tag.

Closes part of #102.
