Vitest was incorrectly running Playwright E2E test files,
causing test suite failures. Added vitest.config.ts to:
- Exclude E2E test folder from unit test runs
- Configure jsdom environment for component testing
- Separate concerns: 'pnpm test' for units, 'pnpm e2e' for E2E
Result: All 176 tests now pass
- Backend: 135/135 (40 unit + 95 integration)
- Frontend: 41/41 (40 unit + 1 E2E)
