Implement Error Handling and Cleanup for Partial Uploads

[ahmadnasriya]

During the file upload process, errors such as network interruptions or server issues can result in partially uploaded files being left on the server. These files should be automatically cleaned up to prevent clutter and potential storage issues.

Task:

Implement robust error handling and cleanup mechanisms to ensure that partially uploaded files are properly handled and removed if necessary.

Steps to Implement:

1. Modify the request handler to detect errors during the upload process.
2. Ensure that any partially uploaded files are deleted if an error occurs before the upload completes.
3. Implement and test scenarios where uploads are interrupted or fail to verify that cleanup works as expected.

Expected Outcome:

The server should automatically clean up any partially uploaded files, preventing storage clutter and ensuring that only fully uploaded files are retained.
