"""重置工艺工序分类（biz_process_category）：清空指定租户数据后插入 5 条初始数据。

用法（在 backend 目录）：
  source venv/bin/activate
  python scripts/reset_process_categories.py
  python scripts/reset_process_categories.py --tenant-no zkxw

注意：biz_process / biz_process_route_step / biz_production_task_step 等表
通过 category_id 引用本表，重置后上述关联 id 会失效（字段可空，不会阻断脚本）。
