fix: upgrade Poetry to 2.2.1 for poetry.lock compatibility

Resolve Docker build failure caused by poetry.lock incompatibility:

**Root Cause:**
- Local Poetry version: 2.2.1
- Dockerfile Poetry version: 1.8.0
- poetry.lock generated with 2.2.1 not compatible with 1.8.0
- Build failed: "Dependency walk failed at triton (==3.5.0)"

**Solution:**
- Upgrade Poetry to 2.2.1 in all Dockerfiles (api, chat, worker)
- Update CI/CD pipeline to match (POETRY_VERSION: 2.2.1)
- Successfully tested Docker build with new version

**Files Modified:**
- deploy/docker/Dockerfile.api
- deploy/docker/Dockerfile.chat
- deploy/docker/Dockerfile.worker
- .gitea/workflows/build.yml
