Convert auth tokens to cookies for client.
- AT use httpOnly, secure, samesite attributes
- RT httpOnly, secure, samesite, and path set to auth/refreshToken to only allow it to be used on that 1 route
- remove this from request.ts as it is likely redundant from cookies
```
// this.axios.defaults.headers.common["Authorization"] =
// `Bearer ${accessToken}`;
```
- Test the server can see the cookie in authGuard
