[nakul-py]

What changed?

• Added a check to verify if the email exists before attempting the sign-in process.
• Display an error message if the email is not registered, prompting users to register a new account.
• If the email is not found, users are provided with a link to the registration tab for account creation.
• Fixes Display an error message on sign in if the email does not belong to a registered user #296

Why?

• This change was implemented to improve the user experience by notifying users immediately when they attempt to sign in with an unregistered email.
• Users no longer need to guess why they can't log in or be confused by no feedback, leading to better usability and fewer failed attempts.

Hey @nakul-py! In order to display the error here, we'll need to update the sign in logic on the backend.

You can look at the Convex Auth docs for email validation for more info: https://labs.convex.dev/auth/config/passwords#email-address-validation
