Can you rebase please @rishuraj1

[rishuraj1]

hey @jain-rishabh-21 since the signup form is totally replaced by login form now, I had to change the login form design and over all ui again. please have a look and I resolved all the conflicts too. I will do the same with the Signup page too.

@jain-rishabh-21 done with changes in both signup and signin and fixed the route, before the route was /signup , changed it to /register as intended. please merge it now.
