fix(formatters): restore bold+underline for alias indicators in short ID column

Replace markdown **bold** syntax with chalk boldUnderline() for alias
highlighting in formatShortId and formatShortIdWithAlias. The markdown
approach only produced bold text; the original used bold+underline via
chalk to make alias indicators visually distinct. ANSI codes survive
the table rendering pipeline and display correctly in TTY mode.
