Make line numbers reflect visual lines, not speaker turns

- Split long lines into multiple visual lines at word boundaries.
- Each visual line is its own paragraph with its own embedded line number.
- Continuous numbering across speakers and pages.
- Portable across Word, LibreOffice, Google Docs.
