Snooze / unsnooze items for an outlet

Temporarily disable or re-enable items for a specific outlet. **Item matching:** Items are matched by `itemCode` → `items.item_code`. **Snooze (disable until a time):** - Send `snoozeEnd` with a RFC 3339 datetime → sets `item_store.disabled_until` - Item is unavailable until that time, then automatically available again ```json { "items": [ { "itemCode": "DIM-001", "snoozeEnd": "2026-03-13T22:00:00Z" }, { "itemCode": "WOK-003", "snoozeEnd": "2026-03-13T14:00:00Z" } ] } ``` **Unsnooze (re-enable immediately):** - Omit `snoozeEnd` or send `null` → clears `item_store.disabled_until` ```json { "items": [ { "itemCode": "DIM-001", "snoozeEnd": null } ] } ``` **Important:** - `sell_available` is NOT modified — snooze is a time-bounded pause, not a permanent toggle
