feat: 商品记忆库 — 从OCR结果学习，逐步替代OCR识别

- 扩展 product_db.py: schema迁移(specification/source/confidence/usage_count/last_seen)
  + 学习逻辑(learn_from_product)、置信度系统、批量查询、导入导出、云端同步
- 注入处理管线: processor.py 在提取产品后调用 _apply_memory() 用记忆补全OCR
  + _is_spec_suspicious() 检测OCR规格质量，处理完后自动学习
- order_service.py 创建共享 ProductDatabase 实例
- dialog_utils.py 新增商品记忆库云端同步条目
- 新建 memory_editor.py: Treeview查看/编辑/搜索/删除/重新导入
- main_window.py 系统设置区新增"商品记忆库"按钮
- build_exe.py 添加 memory_editor 到 hidden_imports
