Fix copying task logs dropping rows that scrolled out of view - #71156

The task log viewer only renders the visible rows. Copying a selection uses the browser's default copy, which serializes only the rows currently in the DOM, so rows the viewer has unmounted are silently missing from the copied text. Rebuild the missing rows from log data, using the same text pipeline as the log download. The rebuild reads row text programmatically, which ignores the CSS that keeps the line-number links out of a normal copy, so strip those links too and leave single-row, fully-mounted, and multi-range selections to the browser.

Why
After #71148, when the user selects and tries to copy task log rows, virtualized rows that scrolled out of view are missing. It's because native copy only serializes mounted DOM.
What
Rebuild missing selected rows from parsed log data with the same plain-text rendering as the log download. Keep native copy for single-row, fully mounted, and multi-range selections.
