refactor(docker): merge two-container setup into single container (#657)

* refactor(docker): merge two-container setup into single container

The Web UI already manages the Hermes Agent gateway lifecycle internally
via GatewayManager (spawn hermes gateway run --replace), making the
separate hermes-agent container redundant. The Dockerfile is built on
the hermes-agent base image, so all CLI tooling is already included.

- Remove hermes-agent service and shared volume from docker-compose.yml
- Remove gateway port mapping (8642-8670) — internal-only now
- Update docs/docker.md, README.md, README_zh.md for single-container setup

* docs: remove version tag from image references

Use ekkoye8888/hermes-web-ui instead of ekkoye8888/hermes-web-ui:latest
to avoid pinning a specific version in documentation.
