Add a read-only "Review and Confirm" page prior to application submission

***Problem Statement***
Currently, applicants must navigate back through previous application screens to review their responses before submitting. This creates a risk that users may unintentionally change information while attempting to verify their answers. It can also make it difficult for users to feel confident that all information entered is accurate before final submission.

***Proposed Solution***
Introduce a dedicated Review and Confirm page immediately before submission.
This page should display all application responses in a read-only format, similar to an online order review or checkout confirmation page. Users can review their information without the ability to edit fields directly.

***Expected User Experience***

1. Applicant completes all required application sections.
2. Applicant selects a Review and Confirm button after the final selection.
3. The Review and Confirm page contains all application responses and all fields are displayed as read-only (non-editable).
4. User reviews their information.
5. If changes are required, the user selects an Edit link to take them back to the relevant.
6. After making corrections, the user is returned to the Review and Confirm page.
7. User selects Submit Application to complete the process.

***Benefits***

Reduces accidental changes when reviewing information.
Increases applicant confidence that their information is accurate before submission.
Aligns with common online experiences such as e-commerce checkout and government application services.
May reduce application corrections, follow-up inquiries, and processing delays caused by submission errors.
Provides a clear separation between entering information and submitting information.

### Acceptance Criteria ###

- [ ] A Review and Confirm page is displayed before final submission.
- [ ] All application responses are visible on a single review page or organized by section.
- [ ] Information is displayed in a read-only format.
- [ ] Users cannot modify responses directly from the review page.
- [ ] Each section includes an Edit option that returns the user to the corresponding page.
- [ ] After editing, users are returned to the Review and Confirm page rather than progressing through all application pages again.
- [ ] The application cannot be submitted until the user reaches and confirms the Review and Confirm page.

***Priority Justification***

This enhancement improves usability, reduces user error, and supports applicants in making informed submissions without increasing application complexity. It is particularly valuable for StudentAid BC applications where errors may affect eligibility assessments, processing timelines, or requests for additional information.

Start by tracing the application flow after the final selection and before submission. Identify how each application section is rendered and how navigation returns after edits. Done means a read-only Review and Confirm page shows all responses, supports section-level editing and return, and blocks submission until confirmation.
