File uploader on Student Create Profile

**User story**
As a _student user_, I want to have access to the file uploader feature so that I can send the Ministry my sensitive personal information.
As a _Ministry user_, I want to view the sensitive attestation form so that I have most or all the documents required to create account for student.

**Acceptance Criteria**

**Student user**
- [ ] Add a simplified file uploader feature on the Create your profile page
- [ ] Document purpose is only for Identity (so no dropdown is required)
- [ ] Documents are displayed in ‘File Uploader’ section when the account is approved by the Ministry user

**Ministry user**

- [ ] Add the file that needs to be viewed to a section on the “Accounts> View request” page

- [ ] Display uploaded file in a new window so the Ministry user can view both screens at the same time (tbd)

**Business context**
BasicBCeID users must upload sensitive identity attestations to SABC to get account approved, but currently have to do so via e-mail as they don't have access to the Document Uploader until their account is fully verified/approved by a Ministry user AFTER their attestation is required.
We want to avoid using email communications involving sensitive student information.
The file uploader feature would need to be built into the page so that the student is not forwarded to another page.
The document purpose is only for Identity attestations so no drop down would need to be selected.
