* fix(relay): judge the reserve watch's 503 rule on non-drain 503s, not a host's own re-dials

The watch counted every director 503, and on 2026-10-18 ~98% were host-rate-limited re-dials that
grow with traffic, so it flipped production-gce-c7 back twice with no fault. It now uses the roll
ladder's non-drain measure (request_count 503s less drain-return deferrals and host-rate-limited /
host-in-flight re-dials from the director's runtime metrics) for both the background and the live
samples. A judged minute no runtime-metrics line covers is unverifiable, not zero.
