tui: add blank interior rows at top and bottom of tool boxes

Body content used to start on the row immediately under the top
edge and end on the row immediately above the bottom edge, leaving
the box visually cramped against its corners.

Insert a blank box-side row (a \u2502 \u2026 \u2502 with no content) after the
top edge and before the bottom edge in both the transcript path
(renderMessage RoleTool branch) and the live overlay path
(renderToolCall, both streaming and finished-with-body). Empty-
bodied boxes (finished call with no result) stay compact \u2014 the top
and bottom edges sit directly adjacent so a no-output tool doesn't
render as a tall hollow frame.
