Allowed signups from any emails

Some good news...

Thanks to the local JS community and Claude Code, I’ve made the Dictate Button component accessible and fixed a bug with setting its default language.

What's more important in this update is that you can now signup to the Dashboard and start your journey with any email (Gmail, Proton or any other). I have replaced email-based access restriction with a domain verification via DNS, so everyone's welcome now!

I appreciate any feedback or advice from you, so don’t hesitate to reach out to me anytime.
