[FEAT] 電子發票作廢權限控管、交易訂單與發票備註、作廢發票差異顯示

1. 發票作廢改為僅限平台系統管理員：voidInvoice() 加 isSystemAdmin() 403 守衛，訂單詳情面板與 tab-invoices 手機卡片作廢按鈕同步加 isSystemAdmin 顯示條件（列印鈕維持所有人可用）。
2. 新增 orders、invoices 各自獨立的 remark 欄位（migration + Model fillable），供管理者編輯內部備註。
3. 新增 updateOrderRemark / updateInvoiceRemark 端點與 PATCH 路由，AJAX 回傳 JSON、租戶隔離沿用 TenantScoped。
4. 訂單詳情面板加入訂單與發票備註的 Alpine 內嵌編輯（fetch + toast，不重整頁面），所有可進銷售中心者皆可編輯。
5. confirm-modal 加可選 slot；作廢確認視窗加備註輸入框，submitInvoiceAction() 送出前注入隱藏 remark，寫入 invoice.remark（不影響送綠界的 void_reason）。
6. 訂單列表（桌面與手機）已作廢發票改以灰色刪除線加「已作廢」標記顯示，index eager load 補載 invoice.status。
7. 新增 5 組三語系 key（Voided、Enter remark (optional)、Remark updated、No remark、Only system administrators can void invoices），zh_TW/en/ja 對齊排序至 2572 鍵。
