Write comprehensive Vitest tests for the provided code.

1. Identify the type of code being tested:

   • Express route → use Supertest patterns
   • React component → use Testing Library patterns
   • Pure function / utility / repository → use Vitest with describe/it/expect

2. Cover:

   • Happy path (expected behavior)
   • Edge cases (empty input, boundary values)
   • Error/failure paths (invalid input, rejected promises)
   • Auth failure (401) for protected routes

3. Follow conventions in testing.instructions.md:

   • Name tests: it('should <behavior> when <condition>')
   • Use vi.fn() / vi.mock() for dependencies
   • Reset mocks in beforeEach(() => vi.clearAllMocks())
   • Query by accessible role in UI tests

Place the test file adjacent to the source file as <filename>.test.ts or <filename>.test.tsx.
