Fetch WHY registry surfaces fail and whether the mix is changing (#9622) -- the classification breakdown (live, redirected, transient, rate-limited, timeout, dead, content-mismatch, unsupported, auth-required) over a window, plus a per-day series. Use it for 'why are these endpoints failing' and 'did timeouts spike this week'. NOT the same as get_health_history, which FILTERS one dated snapshot by classification to list which surfaces were dead on a given day; this one aggregates the reasons themselves. SUCCESSFUL PROBES ARE COUNTED TOO, because a rate needs its denominator -- `share` is of every probe in the window and `failure_share` is of the failing ones only, and failure_share is NULL rather than zero on a succeeding classification. `redirected` is NOT a failure: a surface answering from a new location is serving. days_covered is counted from the rows, so a day the prober did not run is ABSENT rather than a day of perfect health -- read oldest_day/newest_day for what was actually covered. window is 7d, 30d (default), 90d or 180d; netuid scopes to one subnet and kind to one surface kind. An EMPTY window is a measurement, not a failure -- it means the prober recorded nothing in that range, and only `degraded` says the read itself could not be made. Mainnet only.
