Fix syntax highlighting regex order in config editors

The number regex was applied after the boolean regex, causing it to
match "400" in CSS class names like "text-orange-400" and corrupt
the HTML output. Now uses placeholder tokens to mark numbers before
adding any HTML tags.

Affected editors: Palworld, Zomboid, OpenTTD
