fix(langgraph-python-threads): pin to stable @copilotkit/* 1.57.0 and intelligence 0.1.0 (CopilotKit#4663)

## Summary
- Bump `@copilotkit/{a2ui-renderer,react-core,react-ui,runtime}` from
`1.56.5-canary.1777671752` to `1.57.0` in `apps/app/package.json` and
`apps/bff/package.json`
- Bump `ghcr.io/copilotkit/intelligence/composite` from `0.1.0-rc.16` to
`0.1.0` in `docker-compose.yml`
- Align the Dockerfile python pin (`copilotkit==0.1.78`) with
`apps/agent/pyproject.toml` (`copilotkit==0.1.86`)
- Regenerate `package-lock.json` against the new stable npm pins

## Test plan
- [ ] CI's `showcase_validate.yml` passes (or reports an expected
ratchet drop in `validate-pins` baseline that a maintainer can reset)
- [ ] `docker pull ghcr.io/copilotkit/intelligence/composite:0.1.0`
succeeds (verify the literal tag string matches what is published)
- [ ] From `examples/integrations/langgraph-python-threads/`: `npm
install && docker compose up` boots cleanly with the new pins
- [ ] BFF connects to the intelligence composite at `0.1.0` without API
surface drift
