feat(auth): OAuth2 + JWT auth service with Alembic migrations (#5 #7)
- Alembic async migrations: users, conversations, messages, is_favorited
- FastAPI auth service: Google + GitHub OAuth, RS256 JWT, refresh cookie
- /auth/me, /auth/refresh, /auth/validate (service-to-service)
- rate limiting 10/min on OAuth routes, CORS locked to FRONTEND_URL
