Append a CLEAR_TERMINAL_SCROLL_BACK marker on disconnect and consume it in the frontend to effectively clear terminal scrollback. Backend: add marker on client close and in socket provider, import convertFromKilobytesString and use it to format MEMORY and FLASH values in the report, and compute/list missing ports (separating PoE vs SFP) in the summary HTML. Frontend: emit the marker on line_disconnected and have TerminalXTerm replace the marker with multiple newlines (varying by miniSize) before writing/initializing terminal content to scroll to bottom.
