Support for Invisible hCAPTCHA
This PR adds support for invisible hCAPTCHAs by adding a setting toggle that enables it.
Invisible hCAPTCHAs hide the CAPTCHA challenge until the user hits the submit button, and displays the CAPTCHA as a floating window. This allows the unstyled HTML form to blend in better into an existing website. (See https://github.com/knadh/listmonk/issues/2295)
I'm still new to this, so please let me know if a different approach should be taken.
Example demo of invisible CAPTCHA:
Hi @candidexmedia. The PR seems to be broken with syntax errors. Also, I'm planning of integrating https://altcha.org and phasing out hCaptcha in the future.

I see that altcha has a floating UI option, so that's promising. How will it be integrated into Listmonk (since there's no hosted cloud version)?
Closing this as I'm planning to integrate Altcha. It'll be self-contained within listmonk.
