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.

issue 中沒有指定檔案、測試或上傳入口。使用大於 100 MB 的檔案重現逾時，然後追蹤應用程式的上傳路徑以及現有的大型請求處理方式；當上傳完成，或在不發生應用程式逾時的情況下正常失敗時，即表示完成。
