Refactor file upload to use SDK instead of XMLHttpRequest

Replaced manual XMLHttpRequest implementation with the SDK's `uploadFile` method for handling file uploads to presigned URLs. This simplifies the code, leverages built-in features like progress tracking, and improves error handling. Added token extraction and upload progress updates to maintain functionality.
