refactor: 删除板块资金流向，题材板块功能更全

- 删除前端 /sectors 页面、首页入口按钮、stock-api 板块类型与 fetchSectors
- 删除后端 /api/sectors 路由，main.py 移除注册
- eastmoney.py 移除板块数据段(_fetch_push2/_fetch_akshare/UT令牌管理)，
  清理重复 import 与无用 datetime 子导入
- mootdx.py 移除板块降级方案(fetch_sector_list)
- routeTree.gen.ts 由 build 自动重新生成，移除 sectors 路由

题材热点/热点穿透/核心股已覆盖板块能力，功能更全，板块资金流向不再需要
