Fix failing backend test suites for Auth Routes and User Model

[parinaB]

Description

Two backend test files are currently failing. These were discovered while setting up the frontend test suite in #275 and are pre-existing failures unrelated to that PR.

Failing files:

• spec/auth.routes.spec.cjs — Auth Routes
• spec/user.model.spec.cjs — User Model

---

Steps to Reproduce

1. Clone the repo
2. Navigate to the backend directory
3. Run the test suite
4. Observe failures in auth.routes.spec.cjs and user.model.spec.cjs

---

Expected Behaviour

All backend tests should pass.

---

Actual Behaviour

Auth Routes and User Model test suites are failing.

Hi @parinaB and @GitMetricsLab maintainers,
I noticed this issue is currently assigned, so I do not want to interfere with the current assignee’s work.
If any help is still needed or if the issue becomes available, I would be happy to work on it.
I understand that the backend test failures are coming from spec/auth.routes.spec.cjs and spec/user.model.spec.cjs. My approach would be to first reproduce the failing test suites locally from the backend directory, inspect whether the failures are due to test setup, auth route behavior, user model validation, database mocking, or environment configuration, and then make the smallest focused fix required to make both suites pass.
I would also make sure existing backend behavior is not changed unnecessarily and would run the full backend test suite before opening a PR.
Happy to contribute if maintainers need additional support.
