優化採購單與進貨單操作紀錄：新增品項明細、ID 轉名稱解析、前端多數量 key 通用顯示

- 重構 PurchaseOrder@tapActivity：支援 vendor_id/warehouse_id/user_id 自動解析為名稱
- 修改 PurchaseOrderController@store：改用 saveQuietly + 手動日誌，建立時紀錄品項明細
- 修正 PurchaseOrderController update/destroy snapshot 跨模組取值為 null 的問題
- 修改 GoodsReceiptService@store：改用 saveQuietly + 手動日誌，建立時紀錄品項明細
- 修改 ActivityDetailDialog.tsx：支援 quantity/quantity_received/requested_qty 多 key 通用渲染
- 新增項目顯示金額與備註，更新項目增加金額與備註變更對比
