What's Changed

• Fixed the web UI showing raw HTML instead of the page when DnsTube is reached through a reverse proxy that sends X-Content-Type-Options: nosniff, such as Cloudflare Tunnel (#97). The /, /index and /settings pages now send Content-Type: text/html; charset=utf-8.
• If you added a Cloudflare Response Header Transform Rule to work around this, you can remove it after upgrading.

Thanks to @altasnep for the detailed bug report and diagnosis.
