feat(logging): add method + request_path to log metadata

Every Sent log line now carries method and path so noisy traffic
(probes, scrapers, redirects) is identifiable without a tracer.
RemoteIp plug already sets remote_ip metadata; add method and
request_path alongside it and register the extra keys with the
default formatter.
