产品迭代模块：卡片改表格 + 日期内联编辑 + 后端日期校验

- 卡片列表改为表格列表（10列），参考用户运营中心产品台账
- 数据库新增 priority + 5 个日期字段（start/plan/dev_done/test/launch）
- 删除 owner/platform/feature_list 字段（migrate_drop_product_fields）
- 日期内联编辑：5个日期列直接渲染 date input
- 后端日期校验：4个时间不能早于启动时间；启动时间必填
- 详情页新增耗时统计区块（总/产品/研发/测试耗时）
- 优先级和状态合并同一行
- 新增'未开始'状态
- 表格垂直居中对齐
- renderProducts 后重新初始化 lucide 图标
