[FEAT] B009 改為全量同步模式，硬刪除不在清單的貨道

1. 修改 MachineService@syncSlots 實作 B009 全量同步邏輯：同步完成後，找出資料庫中不在 B009 回報清單的舊貨道，先記流水帳再硬刪除，確保後台狀態與機台實體完全一致。
2. 新增 MachineStockMovement::TYPE_DECOMMISSION 常數，用於標識因 B009 全量同步而移除的貨道異動紀錄。
3. 新增多語系翻譯 key（zh_TW / en / ja）：movement.note.slot_decommissioned_by_b009、movement.note.initial_sync_report、movement.note.product_changed_and_adjusted 與 movement.type.decommission。
