- flask_app.py 1166行→33行纯入口
- 新建 db.py（配置+连接+SQL工具）
- 新建 helpers.py（attach_common/monthly_finance/add_file_index）
- 新建 routes.py（全路由 Blueprint + 装饰器 + TABLES）
- 新建 migrations/seed_data.py（seed_db 搬迁）
- migrations/{tables,columns,data_fixes,seed}.py 改 import 为 from db
- 删除死代码 init_db（228行）+ latest_followup（10行）
- 反向依赖消除：migrations 不再 import flask_app
- 前端零改动，URL 不变
