fix(api): complete Docker sandbox tool execution pipeline

- Add linux/arm64 dify-cli binary for Docker containers
- Add DIFY_PORT config field for Docker socat forwarding
- Fix InvokeFrom.AGENT (doesn't exist) → InvokeFrom.DEBUGGER
  in CLI API fetch/tools/batch endpoint

Full pipeline verified: Docker container → dify init → dify execute
→ CLI API callback → plugin invocation → result returned to stdout.
