Add Perfect Weeks as an automatic success metric

My griply is mostly based around habits, and to measure my performance on the insights tab, I have to manually mark that a week was perfect. I see that there’s already a perfect week counter on the habit page, but I’d like this to roll up to the target on the associated goal. Ideally if a goal spans habits in a week, it would be marked as a perfect week if all the habits were completed consistently.
