Fix horizontal box-drawing alignment with textLength attribute

Browse Source 
Horizontal line characters (─━═) render narrower than the intended
character width in most fonts, causing gaps when followed by other
characters. Now using textLength + lengthAdjust='spacing' to force
horizontal box-drawing spans to occupy their correct width.

- Added _is_all_horizontal_box_drawing() helper
- Added textLength attribute for horizontal line spans > 1 char
- Added comprehensive tests for new functionality
- svg_exporter.py now has 100% test coverage
