Merge Application Exception Uploads into File Uploader

**Description:**
Automatically merge any files uploaded through the application into the File Uploader so they can be viewed together with other files.

**User Story:**
As a **_ministry user_** I want to be able to view all files uploaded by the student in a singular place so they can quickly retrieved for review.

**Acceptance Criteria:**
Anytime a student uploads a file through the application,
- [ ] Keep the file embedded within the application so it can be reviewed as part of the application
- [ ] Copy the file to the File Uploads and place under the 'student uploads' section **with a label next to it indicating the application number associated with it.**

Start by tracing the application's file-upload flow and the File Uploader's “student uploads” section. Verify how uploaded files remain available within the application and how the uploader organizes them; the work is done when both views contain each file and the uploader shows its associated application number.
