CTHUB - Provide download option for clean data

**Describe the task**
When users upload their database, the system may, in some cases, make minor adjustments to the file to ensure consistency (e.g., formatting changes like capitalizing column headers). If such adjustments are made, the user must be informed, and an option to download the updated file (Clean Dataset) should be provided

**Purpose**
The purpose of this task is to provide users with the ability to download their updated dataset (Clean Dataset) when the system makes adjustments. This ensures transparency by informing users of any changes to their file and providing access to a consistent, well-formatted version.

**Acceptance Criteria**
- [ ] The ‘Clean Dataset’ download button is available below the window where the uploaded file is displayed, showing the file name, size, and delete option.
- [ ] The ‘Clean Dataset’ available if the file contains no errors, but warnings may be present
- [ ] The ‘Clean Dataset’ download option should only be available when the system has made adjustments to the file.
- [ ] Download button that downloads a csv or excel file with adjustments
