Summary

• Changes the default Blob listing response format from XML to Apache Arrow.
• Treats unset and AUTO formats as Arrow while preserving explicit XML.
• Centralizes ListBlobsOptions copying and default application across sync/async flat and hierarchical listings.
• Preserves options when pagination overrides the page size.
• Adds request-level tests verifying the generated Accept header for all listing paths (null, unset, ARROW, AUTO, and XML`)
• Removes the obsolete error-response-body deserialization test.

Why

Blob listing should use Apache Arrow by default.

Testing

• Added 16 cases covering null, unset, ARROW, AUTO, and XML` across sync/async flat and hierarchical listings.
• Ran targeted tests and Checkstyle successfully.

Isabelle (@ibrandes) tests that are failing in CI right now aren't for the arrow enablement. Those have to do with issues with the service not supporting the features. So I don't know why this is happening. But this should be good now
