Generate tests using pytest + httpx. For each endpoint and method, include:
- Happy path with valid data
- Every documented error response (trigger each status code)
- Boundary values for constrained fields (minLength, maxLength, minimum)
- Type mismatch tests (string where number expected, etc.)
- Missing required field tests
- Invalid enum value tests
- Auth tests (missing token, expired token, wrong role)
