修feat: 渠道库存同步支持字段任意排序并增加字段异常告警

- 按字段名校验并写入渠道库存，取消字段顺序校验及表头重建
- 严格校验必填字段名称、类型和数字格式，失败时不修改表头或记录
- 字段校验失败时发送飞书群通知
- 添加字段校验与通知流程测试
- 忽略 Python 字节码、__pycache__ 和 .DS_Store

 - `.env` 不应提交到版本库。
 - 日志默认不会输出数据库连接信息、飞书 app token、飞书 base URL、表 ID、密码或密钥。
 - `FEISHU_APP_TOKEN` 可选；当 `FEISHU_BASE_URL` 已包含 `/base/` 或 `/wiki/` 时，可以不单独配置。
+- 渠道库存同步允许飞书字段任意排序，但会严格校验必填字段名称、类型和数字格式。校验失败时不会修改表头或记录，并会向指定的飞书通知群发送错误消息。应用需开启机器人能力、具备发送群消息权限，并已加入该通知群。
