OAuth in Development Env

[dayfine]

Right now the OAuth workflow works if we posts the request to 'localhost:3001/api/auth/google'. However, the proxy setting I tried so far (both client/server ones) cannot correctly redirect the 'localhost:3000/api/auth/google' request to port 3001.

This should not be a problem for production. But we need something that works for the development workflow.

Right now, it is solved by explicitly using '//localhost:3001/api/oauth' as url for google login.
This should be changed before deployment.

Signup doesn't workout very well right now (or more like not addressed/tested)

google callback should be redirected to jwt token verify route for authentication
