Redirect to homepage if user doesn't have studio permission

[hanzlamateen]

Currently it displays a blank page. Ideally it should redirect to homepage where user should login. And once user has logged in then he should be redirected back to studio.

Same behavior should be done for admin panel.

If there is any redirect url in the query params of homepage, then it should show message that after login, you will be redirected to thats url.
