CTHUB - Implement Download Button for Error and Warning Results After Dataset Upload

[Lalita-Lala]

Describe the task
After a user uploads their Dataset, the system displays the results in the form of errors and warnings. These results are presented to the user with an option to expand or collapse the detailed information via “Show More” and “Show Less” buttons. To enhance user convenience, we need to implement a “Download Error and Warning Results” button.
This button should always be visible in the error & warnings section of the page, located below the initial list of errors and warnings, but above the detailed descriptions. Even when the user expands (“Show More”) or collapses (“Show Less”) the details, the button should remain in its fixed position above the expanded content, making it easily accessible. After downloading the file, users will see their errors and warnings, ideally separated into two different sections or pages within the file.

Purpose
The purpose of this task is to allow users to download their error and warning results in a structured file. The button should remain easily accessible, even when users scroll through or expand/collapse the details, ensuring they can download the results at any point.

Acceptance Criteria

• A “Download Error and Warning Results” button is implemented and located in the error & warnings section, just below the list of errors and warnings, and above the detailed descriptions.
• The button remains in a fixed position, visible at all times, regardless of whether the user clicks “Show More” or “Show Less” to expand or collapse the error and warning details.
• When the user clicks the button, they can download a file containing both errors and warnings, separated into two distinct sections or pages.
• The button becomes available after the system finishes processing the uploaded database and the error/warning results are displayed.
• Spreadsheet should be the file format of choice
