[TranceLove]

Summary

As documented in https://developers.google.com/drive/api/reference/rest/v3/about/get, the fields parameter is required, hence setting fields = storageQuota for quota query to succeed.

Thanks so much, @TranceLove!

Would you mind signing your commit? You can follow [these instructions](https://docs.github.com/en/authentication/managing-commit-signature-verification/signing-commits) if needed.

Also, I've added a few suggestions below from Copilot — feel free to take a look.

One quick thought: do you think this feature should be surfaced in the sample app? Totally okay if you can't take it on right now, but if you think it's worth including, would you mind opening a tech debt issue so we can track it for later?

Appreciate your help! 🙌

• [nitpick] For consistency with the repository code, consider referencing the STORAGE_QUOTA constant defined in NonGmsFileRepository.kt rather than using the literal "storageQuota" string in tests.
