Issue: feat(authn): Use cookies for authentication

Currently we use auth headers and local storage in FE for transfer JWT from FE to BE.

Cookies is a better way to do this, as it is handled by browser and JavaScript doesn't have access to.

First we will test this in Integ and slowly move it to sandbox and production.
