新增「车间班次」功能（前缫车间排班配置）

后端
- 新增实体 ChejianBanci（表 ChejianBancis：车间 / 班次 / 日工作小时数）
- 新增 ChejianBanciService 与 ChejianBanciController（api/prod/chejianbanci）
  分页列表、编辑回显、新增、修改、删除、前缫车间下拉；含必填校验与同车间同班次重复校验
- 菜单种子：基础数据 → 车间班次（Timer 图标，权限 base:chejianbanci:list）
- 修正历史数据：名称以「前缫」开头的部门职责类型改为「前缫」(25)。
  迁移时 duty_type 被统一写成「其他」，导致按职责类型筛选车间取不到数据

前端
- 新增 web/src/views/base/chejianbanci/index.vue（列表 / 搜索 / 分页 / 新增 / 编辑 / 删除）
- 注册组件映射 base/chejianbanci/index
