fix: add proper error checking to meal-plans test setup

- Add .expect() assertions to all registration and login calls
- Add validation that userId and authToken are properly set
- Add error checking to meal plan creation in beforeEach hooks
- This will produce clear error messages instead of cryptic "Cannot read properties of undefined" errors
- Helps identify root cause of 401 authentication failures
