feat(logging): 日志持久化落盘(LOG_FILE 滚动文件)

- LOG_FILE 配置: 空(默认)保持 stdout + Admin 内存日志页(重启清零);
  填路径后额外写 RotatingFileHandler(单文件 10MB × 5 份,utf-8)
- setup_logging 幂等挂载(按 abspath 判重,相对/绝对同文件算一个);
  目录自动创建;文件基础设施失败只 warning 绝不拖垮启动
- docker-compose: api 挂 applogs 卷,默认 LOG_FILE=/app/logs/app.log,
  容器重建日志不丢;.env.example/.gitignore/docs 同步
- tests/test_log_persistence.py: 落盘/幂等/空值禁用/自动建目录/失败降级
- test_p0_standings_cutoff: 匿名约束 name=None 使 any() 子串匹配 TypeError
  (集合顺序不定 → flaky),先判真值再匹配(存量缺陷顺手加固)
