Add option to pass storage config to polars lazy read

### Feature Request / Improvement

I was not able to use the `table.to_polars()` method because there is no option to include a storage_options param which is mentioned in the [polars docs](https://docs.pola.rs/api/python/dev/reference/api/polars.scan_iceberg.html).

从 table.to_polars() 的实现开始，跟踪它如何调用 Polars 的惰性读取路径。查看 issue 中链接的 Polars scan_iceberg 文档，了解 storage_options 接口。完成的标准是：调用方可以通过 table.to_polars() 提供 storage_options，该选项能够传递到惰性读取操作，并且相关测试已更新或添加。
