Allow custom web fonts (Google Fonts, etc.) in the Visual template editor

Hey! First off, love Listmonk — it's become my go-to for managing newsletters.

One thing I've been running into: the Visual editor has a limited set of fonts available, and there's no way to add custom web fonts (like Google Fonts). In an HTML template I can manually add an @import or a <link> and it works fine, but when working in Visual mode there's no equivalent option.

It would be great if the Visual editor supported adding custom web fonts, maybe something like:

• A setting in the Visual template editor where you can provide a Google Fonts URL (or any web font URL)
• The editor automatically generates the proper font-stack with email-safe fallbacks
• Maybe even a small notice reminding users that web fonts are only supported by some email clients (Apple Mail, iOS Mail, Thunderbird…) and that Gmail/Outlook will fall back to the system font

This way, users get the best of both worlds: a nice font for clients that support it, graceful degradation for the rest, and no need to switch to raw HTML just to change a typeface.

Would love to hear if this is something that could be considered. Happy to help spec it out further if needed!
