[FEAT] 遠端指令中心優化與規格同步

1. 實作遠端指令去重機制 (Supersede)：避免重複下達相同待執行指令。
2. 修正遠端指令發送後的 Toast 提示邏輯，確保頁面跳轉後正確顯示回饋。
3. 增加 RemoteCommand 操作者 (user_id) 紀錄與狀態列舉擴充 (superseded)。
4. 修復機台列表「最後頁面」欄位對照錯誤，同步更新 Machine Model 與 API 規格。
5. 優化遠端指令中心 UI：放大卡片字體、調整側面欄間距，符合極簡奢華風規範。
6. 更新 API 技術規格書 (SKILL.md) 與 config/api-docs.php，補全所有機台代碼 (66-611) 與指令。
7. 補全繁體中文、英文、日文多語系翻譯檔案。
