Fix Python CLI .env priority and BOM handling

Allow `.env` values to override existing environment variables, matching the documented priority order. Also read `.env` with `utf-8-sig` and strip a possible BOM from key names for better Windows compatibility.

允许 `.env` 中的值覆盖已有环境变量，以符合文档中声明的优先级顺序。同时使用 `utf-8-sig` 读取 `.env`，并清理 key name 中可能存在的 BOM，以提升 Windows 兼容性。
