Captcha providers for built-in auth UI

[pspsdev]

Currently if you want to add captcha you would need to implement your own UI for auth. Add integration with most popular captcha providers e.g cloudflare turnstile, hcaptcha

Thanks for the recommendation! At the moment, we'd like to keep the built-in UI mostly focused on quick iteration on simple projects since we feel like most projects of any real size want to build out a more customized UI. In the short term, we're likely to make it easier to build a custom UI rather than adding more configuration and flexibility to the built-in UI.

I'm going to close this as not planned for now, but keep an eye out for updates that make implementing your own custom UI easier.
