refactor: create DockerfileTest with hot-reload support and volume mounts

- Rename Dockerfile to DockerfileTest for development variant
- Remove poetry.lock from COPY (regenerated during build)
- Add --reload flag to uvicorn for development
- Add src volume mount in docker-compose for hot-reload
- Update docker-compose to use DockerfileTest
