Security: Enhance Signup and Login Processes with Email Domain Validation.

[smog-root]

Revamp the current signup and login workflows to incorporate email domain validation. Restrict signups and logins to users with email addresses from trusted providers (e.g., Gmail, Outlook).

During the signup phase, extract the domain from the user’s email address and check it against a predefined list of approved providers. If there is a match, allow the signup to proceed; otherwise, present an error message.

i'm expecting a gssoc-ext with level3 and a hacktoberfest-accepted label!
