refactor: inline visible alias in _LivePanelBase._build_body

The `visible = self._scroll_lines[-_MAX_VISIBLE_SCROLL:]` local was
read exactly once as the iterable of the very next `for line in ...`
loop. Collapsing to `for line in self._scroll_lines[-_MAX_VISIBLE_SCROLL:]:`
matches the inline-alias pattern from 497c028 / fc5e1cb / 52e0272 /
ce487d3 / e1ad87a — the slice already documents "the last N scroll
lines" without needing a named intermediate.
