完善机组车台功能，并导入机组车台 / 车间班次数据

一、机组车台功能完善
- 车间下拉改为只取「前缫」职责类型的部门（新增接口 /api/jizuchetai/qianxian-deps）
- 补齐校验：车间、机组号、开始车台号必填；结束车台号不得小于开始车台号；同车间同机组不可重复
- 前端页面同步调整：车间改为下拉选择、增加必填提示、表格加 row-key

二、数据导入（新增 ProdSeedData，幂等导入器）
- biz_prod_qs_jzct：机组车台 35 条（其中 11 条已删除）→ 有效 24 条
- biz_prod_qs_cjbc：车间班次 7 条（其中 1 条已删除）→ 有效 6 条
- F9 的部门 Id 通过部门名称映射到本系统部门；已删除的数据不导入；
  已存在且一致的数据不重复写入，缺失的自动补回
