* security: fix for code scanning alert no. 11: Incomplete multi-character sanitization

Co-authored-by: Copilot Autofix powered by AI <62310815+github-advanced-security[bot]@users.noreply.github.com>

* fix: use dotAll flag to match multi-line HTML comments

Add the 's' flag to the comment-stripping regex so '.' matches
newlines, ensuring comments spanning multiple lines are also removed.
