feat(backend): 库存三态落库（stock/on_sale/sold）——挂售可控 + 卖光留痕

- inventories 加 status 枚举列（默认 stock，AutoMigrate 存量即全部「库存」）+ 索引
- 出库审核扣光置 sold 不再软删（留痕台账）；退单恢复行置回 stock；盘亏仍软删
- 新接口 PUT /inventory/:id/status（仅收 stock/on_sale，已售行拒改，租户校验）
- List 默认排除已售（显式 status=sold 才显示）+ status 多值筛选
- Summary：SKU/货值/数量排除已售，新增 sold_count
- 公开店铺页/API 只列 on_sale——酒单从全量裸奔改为人工精选
- 测试：卖光置售/部分不改/退单回库/接口边界/跨租户/汇总口径 8 用例
- 设计方案 docs/design/inventory-sale-status.html + db-schema/CLAUDE.md 同步
