WalkthroughMachine-a-Tron removes terminal UI support, TUI logging, and related APIs. Runtime shutdown now uses signals. DPU IP accessors replace host-detail parsing. Obsolete interface, TUI, and single-BMC mock settings are removed from configurations and documentation. ChangesMachine-a-Tron cleanup

- Around line 76-82: Keep the issue log numbering consecutive by renumbering the
later stage-3 entry currently labeled 19 to 18, or add the missing issue 18 with
its complete details. Ensure all subsequent issue references and numbering
remain consistent with the complete traceable log.

The terminal UI was an interesting feature, but it did not receive enough community support and was rarely used in day-to-day workflows. This PR removes the TUI to make the machine-a-tron codebase easier to maintain and reduce its dependency footprint.
