Application timeout during file upload

Uploads larger than 100 MB fail with a timeout error instead of completing successfully.

**Steps to reproduce:**
1. Attempt to upload a file larger than 100 MB through the application.
2. The upload begins but does not complete.

**Expected behavior:**
Large file uploads (100 MB+) should complete successfully, or the application should handle them gracefully (e.g. via chunked/streaming upload) instead of timing out.

**Actual behavior:**
The application times out during the upload and the operation fails.

No files, tests, or upload entry points are named in the issue. Reproduce the timeout with a file larger than 100 MB, then trace the application's upload path and existing handling for large requests; done means the upload completes or fails gracefully without an application timeout.
