feat(scale): 实现调料槽位配置持久化及主从设备数据同步

- 新增 SeasoningSlotEntity / SeasoningSlotDao,独立存储格子调料配置
- AppDatabase 升级至版本 8,添加 MIGRATION_7_8
- ScaleEvent 新增 TYPE_SEASONING_CONFIG 和 SlotConfig,用于主从同步
- SeasoningConfigFragment 选择调料后写 Room 并通过 wsClient 推送给子设备
- ScaleWebSocketClient 新增 sendToAllSlaves / sendToDevice / onDeviceConnected
- ScaleWebSocketServer 扩展 onMessage 支持接收主设备下发的配置事件
- ScaleServiceManager 暴露 sendSeasoningConfig / onSeasoningConfig;子设备连接时自动推送全量配置
- MasterScaleActivity 启动时从 Room 加载 slotNameMap,注入 ScaleData.name 展示调料名
- SlaveActivity 新增 slotNameMap 防止重量回调覆盖调料名;监听 onSeasoningConfig 写 Room 并刷新 adapter
- Adapter 新增 tvAddress 和 showAddress 参数,仅 MasterScaleActivity 显示秤地址行;tvName 空值统一显示"-"
