Add test script for large file asynchronous post-processing
- Implemented a comprehensive test script to validate the new asynchronous handling of large file uploads (>1GB). - The script checks for immediate HTTP responses, verifies server configurations for deduplication and virus scanning, and ensures server responsiveness during rapid uploads. - Included checks for relevant response headers and session tracking. - Documented the problem being solved, implementation details, and next steps for deployment and monitoring.
