[FEAT] 電子發票後台開立、對帳、補開與作廢流程

1. 新增發票狀態機（pending/issued/failed/void）與冪等鍵 relate_number，並補上 last_checked_at、retry_count、voided_at、void_reason 欄位（migration 全欄位 nullable/有預設，對既有資料零影響並回填既有狀態）。
2. finalize 帶入發票輸入時改為先建 pending 發票，commit 後派發 IssueInvoiceJob 非同步向綠界開立，避免在交易內等待 ECPay 造成長交易。
3. 新增 EcpayInvoiceService 封裝綠界 B2C API（GetIssue 查詢、Issue 補開、Invalid 作廢），金鑰仍取自各機台 payment_configs。
4. 新增 invoices:reconcile 排程指令，每 5 分鐘對 pending 發票以 RelateNumber 向綠界 GetIssue 查證，補登 issued 或標記 failed 待補開。
5. SalesController 新增 reconcileInvoice/reissueInvoice/voidInvoice 三個後台操作端點與對應路由。
6. 發票列表改以 created_at 篩選（pending/failed 尚無 invoice_date 也能顯示），新增狀態過濾器與查詢/補開/作廢操作按鈕，狀態徽章改以狀態機顯示。
7. recordInvoice 改以 flow_id updateOrCreate 收斂，避免重送產生重複發票列；查詢機台/訂單時加上 withoutGlobalScopes。
8. 同步新增相關三語系字串並加入 ecpay_invoice base_url 設定。
