Scale box-drawing characters vertically to fill line height

Browse Source

Box-drawing characters (│┃║┌┐└┘├┤etc) are designed to connect between
lines but the font's em-box is smaller than our line-height (14px vs
16.8px), creating visible gaps.

Solution: Render box-drawing characters as separate text elements with
a vertical scale transform of 1.2 (matching line-height) to stretch
them to fill the full cell height and connect properly.

This fixes disconnected vertical lines and corners in TUI applications.
