/**
 * v1.4.25 W17b — Withings activity-sync end-to-end.
 *
 * Drives `syncUserActivity` against a mocked Withings response and the
 * real Postgres testcontainer. Asserts:
 *   - Per-day activity entries map to one row per (date, metric)
 *   - The composite-unique with NULLS NOT DISTINCT serializes a
 *     second sync of the same window into UPDATEs (no duplicates)
 *   - Activity rows leave sleep_stage NULL so they do not collide
 *     with the W17c sleep rows
