Admin login: remove button and use /admin as an entry point
It's been confusing for users to see a login button but not being able to access with their old credentials.
That button is supposed to be used by admins to login. Also, we haven't migrated users' data from the old website (because we cannot for legal reasons).
Therefore, we should remove the button and use a hidden path for admins login, ie /admin
