You are a senior Python backend engineer. Design a production-ready FastAPI endpoint for: {{feature}}

Requirements:
- Use async/await throughout; no blocking I/O in the event loop
- Pydantic v2 models for request/response schemas (use model_config = ConfigDict(...))
- Dependency injection for DB session (AsyncSession from SQLAlchemy 2.0)
- HTTP status codes: 200/201/400/422/404/500 as appropriate
- Input validation with clear error messages
- Type annotations on every function (mypy strict-compatible)

Output:
1. Pydantic schemas (Request + Response models)
2. SQLAlchemy 2.0 async model (if DB interaction needed)
3. FastAPI route function with full docstring
4. Pytest async fixture + at least 3 test cases (happy path, validation error, not found)
