• parse chunk granularity from query responses so that user-provided chunk size on resume can be aligned to the server's granularity when present
• stop populating the Authorization header for query, upload, and finalize commands, as it's only required for start
• consolidate header name constants and parseChunkGranularity (now used in both start and query) into a new ResumableUploadHeaders class

Code Review

This pull request refactors HTTP/JSON resumable upload logic by introducing a shared ResumableUploadHeaders utility class to centralize header constants and parsing logic. It also updates ResumableUploadChunkCallable and ResumableUploadQueryStatusCallable to omit credentials and reset the EndpointContext for self-authenticating session URLs. Additionally, chunk granularity parsing has been integrated into the query status flow, and corresponding unit tests have been added. Feedback suggests avoiding the use of HttpJsonStatusCode.of when creating a StatusCode for internal exceptions to prevent incorrect classification of errors as recoverable, recommending an anonymous implementation of StatusCode instead.
