Charlie Marsh b6e153c985 Render only visible rows in the transcript pager (#39063) ...

## Why

Scrolling the transcript pager previously rendered a scratch buffer containing
all rows through the visible viewport, including hidden content above it. This
made rendering work and buffer size grow with the scroll offset.

## What changed

- Add viewport-aware rendering for committed transcript cells and the live tail.
- Forward scrolled rendering through cached and inset renderables while keeping
  the full-height fallback for renderables that do not support it.
- Keep hyperlink metadata aligned with scrolled text.

## Testing

Add coverage comparing viewport-aware output with the full-height fallback
across wrapping widths, offsets, insets, styles, hyperlinks, and live tails.
