Create register and forgot password pages

[shivankacker]

create a register page that accepts email, username, password, full name. This should be identical to the /login page.

Create a /forgot-password page, accepting an email address.

Create a /reset-password page, that accepts an OTP and user_id in the query params. First, make a request to /verify-forgot-token to fetch username and email. Once that is done, load the page and show change password for <user> title accepting a password and reenter password field. Perform the reenter validation at frontend.

Once complete, redirect to /login.

Club all of these pages inside an (auth) group along with the login page in app directory, sharing the same layout for ease of development.
