fix: suppress console.error in error-testing scenarios

- Add console.error mocking to cookbooks.routes.real.test.ts
- Re-enable meal-plans.routes.test.ts with console.error suppression
- These tests intentionally trigger errors to test error handling
- Suppressing console.error prevents noise in CI output while tests still validate behavior

Fixes stderr noise in pipeline from intentional error tests
