fix(ops): tune aggregation constants to prevent PG overload

Browse Source 
Increase MAX(bucket_start) query timeout from 3s to 5s to reduce
timeout-induced fallbacks. Shrink backfill window from 30 days to
1 hour so that fallback recomputation stays lightweight instead of
scanning the entire retention range.
