test(bruno): add token handling scripts to auth endpoints

Add after-response scripts to automatically save access and refresh tokens to Bruno environment variables after successful authentication. This eliminates manual token copying during testing.

Changes:
- Refresh Token.yml: Add script to save tokens from refresh response
- Register User.yml: Add script to save tokens from registration response
