Space/PageDown in the transcript view continues scrolling past the last line. It should stop at the bottom of the transcript content.

## Summary of Changes

In `src/tui/screens/transcript.rs`, the PageDown/Space handler now clamps scroll to the actual content length: computes `total_lines = build_chat_lines(...).len()` and `max_scroll = total_lines.saturating_sub(page_height)`, then applies `.min(max_scroll)` to prevent scrolling into empty space. Updated 3 existing tests to populate entries before testing scroll behavior.
