Replace uvicorn with gunicorn + UvicornWorker in backend, runtime, and schedule Dockerfiles. New gunicorn.conf.py per service exposes bind/workers/timeout/graceful_timeout as GUNICORN_* env knobs. Notable details: - schedule: timeout=0 (disables gunicorn worker heartbeat) so long notebook execution isn't killed by gunicorn's silent-worker kill. - All three configs: drop dead threads=4 setting; UvicornWorker is async and ignores threads. - Pin gunicorn>=26.0.0 in each pyproject; uv.lock regenerated. - Drop stale 'COPY contracts ./contracts' from runtime and schedule Dockerfiles (contracts dir was deleted in an earlier refactor; builds would have failed). - backend Dockerfile: switch to uv sync layout matching runtime/ schedule; add build deps for native wheels.

Backend
统一 FastAPI 管理服务。包含用户、Workspace、脚本、稳定版本、调度定义、
立即运行以及 RustFS 对象接口。原 platform_api 与 storage_api 已在此
模块合并,外部 REST 契约保持不变。
