View habits improvements?

[ManpreetSL]

1. What happens with non-binary habits over 100% completion? How will we display that, celebrate it, etc. in the UI?
2. How are streaks calculated when there's a habit that is 2 days per week, for example? Is it still per sessions that they've done, so if they completed the habit twice per week for 3 weeks, it'd be a streak of 6?
