Marc-André Bombeck 5fa18a3754 feat(measurements): 10-minute aggregated heart-rate upload contract
Refine the go-forward aggregated HR wire contract (iOS #34) from the never-
adopted hourly bucket to a 10-minute UTC bucket, so one contract serves both
the measurements-list de-explosion and the intraday-pulse 10-min curve.

- Batch route accepts stats:HKQuantityTypeIdentifierHeartRate:<10-min ISO-Z>
  with avg + min/max, overwrite semantics, malformed-suffix rejection; the
  validator is identifier-generic (allowlist) so respiratoryRate/SpO2 can join
  later without a grammar change.
- The intraday reader classifies a day's PULSE rows three ways by externalId
  shape (raw / uploaded 10-min bucket / server-folded hourly), builds the
  10-min curve directly from uploaded buckets with the min/max envelope and
  tension detection enabled, and overlays buckets over raw on the one
  cutover-straddling day.
- DAY rollup min/max read COALESCE(value_min, value) so a bucket-native day's
  band reflects the true intra-bucket extremes.

No schema change (value_min/value_max exist since v1.19.2). Reconciliation is
go-forward cutover; the nightly retention fold handles the raw backlog.
