title: Implement Unit & Integration Tests

Add comprehensive unit and integration test coverage to both the backend (FastAPI/Python) and frontend (React/TypeScript). The project currently has zero tests — pytest is configured in pyproject.toml with pytest-asyncio and httpx, but no actual test files exist. The frontend has no test tooling at all.

**Scope:**
- Unit tests for isolated logic (schemas, services, utilities)
- Integration tests for API endpoints (using httpx AsyncClient against a test database)
- Frontend unit/component tests (using Vitest + React Testing Library)

**Explicitly out of scope:**
- End-to-end / browser tests (e.g. Selenium, Playwright) — requires specialised infrastructure

## Success Criteria

- [ ] Backend test infrastructure is set up (conftest, fixtures, test DB)
- [ ] Backend schemas and services have unit test coverage
- [ ] Backend API endpoints have integration test coverage
- [ ] Frontend test infrastructure is set up (Vitest, RTL)
- [ ] Frontend utilities and hooks have unit test coverage
- [ ] Frontend components have basic render/interaction tests
