The command-line history dropdown was display-only, so users had to
screenshot and OCR the log to report output. Make it copyable:
- Render the whole backlog in one read-only text_editor so a single
mouse drag selects across lines and Ctrl+C copies the span.
- Add Copy (whole log to clipboard) and Clear buttons to the dropdown.
- Gate the Ctrl+C/X/V accelerators on event Status::Ignored so a focused
text widget's copy/cut/paste wins instead of firing COPYCLIP/CUTCLIP;
the drawing's clipboard shortcuts still work when it has focus.
