feat(mill): 完成工艺管理与生产计划全栈业务模块

- 新增三张业务表 SQL：mill_process_recipe / mill_process_pass / mill_production_plan
- 后端：Domain + Mapper + MyBatis XML + Service + Controller（工艺方案 & 生产计划）
- 生产计划支持队列排序（sortNo）、上移/下移、软删除
- 工艺方案支持道次批量保存、事务管理
- 前端：工艺管理页（左侧方案列表 + 右侧表单 + 道次内联表格）
- 前端：生产计划页（轧制队列 + 轧制工艺展示 + 操作面板 + 底部带卷状态栏）
- 注册 /mill/process 与 /mill/plan 前端路由
