Security: Revise Signup and Login Processes for Email Domain Validation.

[smog-root]

Update the current signup and login processes to include email domain validation. Limit access to users with email addresses from reputable providers (e.g., Gmail, Outlook).

During the signup process, extract the domain from the user’s email address and compare it against a predefined list of trusted providers. If a match is found, proceed with the signup; if not, display an error message.

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