🐛 Fix hyphens stripped from export filenames (#8944)

Replace str/slug with a targeted regex that only removes
filesystem-unsafe characters when generating export filenames.
The slug function strips all non-word characters including hyphens,
causing names like "my-board" to become "myboard" on export.

Fixes #8901
