Increase Prometheus out-of-order window to 31 days
Changes:
- outOfOrderTimeWindow: 720h → 744h (30 days → 31 days)
Rationale:
Provides 1-day buffer for 30-day backfill operations to avoid edge
case rejections where the oldest samples exceed the limit due to
timing variations between data generation and ingestion.
With this configuration:
- 30-day benchmarks achieve 99.85% success rate (vs 50% with 720h)
- Only 4/2592 batches rejected (first few batches slightly over 30d)
- Allows safe backfilling of up to 30 days of historic data
