feat: Sprint 1 — infrastructure + test creation

Backend: - FastAPI + SQLAlchemy 2.0 async + Alembic - Models: Test, Question, Answer - API: GET /api/tests, GET /api/tests/{id}, POST /api/tests - Pydantic validation: min 7 questions, min 3 answers, ≥1 correct Frontend: - React 18 + TypeScript + Vite + Ant Design + TanStack Query - Pages: TestList, TestCreate (nested Form.List), TestDetail Infrastructure: - Docker Compose: db (postgres:16), backend, frontend, nginx - Nginx: /api/ → FastAPI, / → Vite dev server with HMR - Alembic migration 001_init: tests, questions, answers tables - entrypoint.sh: wait for db, migrate, start uvicorn Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com>
