Add dashed border style

Browse Source 
New --border=dashed / --list-border=dashed / --header-border=dashed etc.
Uses U+2576 (╶) for horizontal edges and U+2506 (┆) for verticals, with
rounded corners (╭╮╰╯) and sharp T-junction mids (├┤). Terminal cells
are taller than wide (~2:1), so horizontals use a sparse stub per cell
while verticals need more dashes per cell to look evenly dashed.
Works with inline sections.
