themes: add tok-attributeName color to 15 themes that were missing it

The Typst grammar now emits CodeArgKey (mapped to tok-attributeName) for
named argument keys like 'columns:', 'align:', 'caption:'.  15 of 41
editor themes had no .tok-attributeName rule, so those keys appeared in
the default text color (black) despite the correct CSS class being set.

Chose colors that complement each theme's existing palette:
light themes → warm dark-orange family (#994409 / #7B3814 / #735C0F)
dark themes  → each theme's accent color (gold, warm red, lavender…)
