Changes Summary

This PR updates the Python SDK’s “list studies” behavior by moving get_studies filter handling fully to the server (always sending the filter field, including null) and aligns the studies list response model naming by renaming StudiesResult.total to StudiesResult.total_records.

Changes:

• Always include search_study_name in the get_studies request body (encoded as JSON, null when unset).
• Rename StudiesResult.total to StudiesResult.total_records and update service usage accordingly.
• Update (commented-out) test expectations and naming to match the new request/response shape.
