The payload-breakdown and top-observers matviews stored a single 7-day total per group, so the 24h/7d/30d selector did nothing: payload ignored the window entirely (the store discarded `since`) and top-observers only varied which rows cleared the last_heard cutoff, never the counts. Bucket both views by hour over a 30-day horizon and sum the buckets in range, mirroring mv_hourly_iata_stats. The stats endpoints now honour the requested window while still reading a small precomputed table.
